* [PATCH v43 6/7] Fix a few problems in index build progress reporting. @ 2026-03-16 12:53 Antonin Houska <[email protected]> 0 siblings, 0 replies; 937+ messages in thread From: Antonin Houska @ 2026-03-16 12:53 UTC (permalink / raw) First, index_build() should not update the progress when being driven by REPACK, because the progress reporting infractructure cannot handle status of two commands at the same time. So far, REPACK with the CONCURRENTLY option neglected this problem altogether, but even the existing REPACK wasn't consistent enough: even if the 'progress' variable in repack_index() was false, it didn't pass the value to index_build(). Second, REPACK (CONCURRENTLY) should not set PROGRESS_REPACK_PHASE to PROGRESS_REPACK_PHASE_FINAL_CLEANUP in rebuild_relation() because it calls finish_heap_swap() anyway (via rebuild_relation_finish_concurrent()), which does the same thing. --- src/backend/bootstrap/bootstrap.c | 2 +- src/backend/catalog/heap.c | 3 ++- src/backend/catalog/index.c | 22 ++++++++++++++++++---- src/backend/catalog/toasting.c | 3 ++- src/backend/commands/cluster.c | 7 ++++--- src/backend/commands/indexcmds.c | 1 + src/include/catalog/index.h | 4 +++- 7 files changed, 31 insertions(+), 11 deletions(-) diff --git a/src/backend/bootstrap/bootstrap.c b/src/backend/bootstrap/bootstrap.c index 68a42de0889..1c8226c6d67 100644 --- a/src/backend/bootstrap/bootstrap.c +++ b/src/backend/bootstrap/bootstrap.c @@ -1181,7 +1181,7 @@ build_indices(void) heap = table_open(ILHead->il_heap, NoLock); ind = index_open(ILHead->il_ind, NoLock); - index_build(heap, ind, ILHead->il_info, false, false); + index_build(heap, ind, ILHead->il_info, false, false, false); index_close(ind, NoLock); table_close(heap, NoLock); diff --git a/src/backend/catalog/heap.c b/src/backend/catalog/heap.c index 5748aa9a1a9..ae6b7cda3dd 100644 --- a/src/backend/catalog/heap.c +++ b/src/backend/catalog/heap.c @@ -3570,7 +3570,8 @@ RelationTruncateIndexes(Relation heapRelation) /* Initialize the index and rebuild */ /* Note: we do not need to re-establish pkey setting */ - index_build(heapRelation, currentIndex, indexInfo, true, false); + index_build(heapRelation, currentIndex, indexInfo, true, false, + true); /* We're done with this index */ index_close(currentIndex, NoLock); diff --git a/src/backend/catalog/index.c b/src/backend/catalog/index.c index 98d38dc5229..1d28202de34 100644 --- a/src/backend/catalog/index.c +++ b/src/backend/catalog/index.c @@ -715,6 +715,9 @@ UpdateIndexRelation(Oid indexoid, * already exists. * INDEX_CREATE_PARTITIONED: * create a partitioned index (table must be partitioned) + * INDEX_CREATE_REPORT_PROGRESS: + * update the backend's progress information during index build. + * constr_flags: flags passed to index_constraint_create * (only if INDEX_CREATE_ADD_CONSTRAINT is set) * allow_system_table_mods: allow table to be a system catalog @@ -760,6 +763,7 @@ index_create(Relation heapRelation, bool invalid = (flags & INDEX_CREATE_INVALID) != 0; bool concurrent = (flags & INDEX_CREATE_CONCURRENT) != 0; bool partitioned = (flags & INDEX_CREATE_PARTITIONED) != 0; + bool progress = (flags & INDEX_CREATE_REPORT_PROGRESS) != 0; char relkind; TransactionId relfrozenxid; MultiXactId relminmxid; @@ -1276,7 +1280,8 @@ index_create(Relation heapRelation, } else { - index_build(heapRelation, indexRelation, indexInfo, false, true); + index_build(heapRelation, indexRelation, indexInfo, false, true, + progress); } /* @@ -1455,6 +1460,12 @@ index_create_copy(Relation heapRelation, Oid oldIndexId, Oid tablespaceOid, stattargets[i].isnull = isnull; } + /* + * Note: The current callers do not need INDEX_CREATE_REPORT_PROGRESS.

Second, REPACK (CONCURRENTLY) should not set PROGRESS_REPACK_PHASE to PROGRESS_REPACK_PHASE_FINAL_CLEANUP in rebuild_relation() because it calls finish_heap_swap() anyway (via rebuild_relation_finish_concurrent()), which does the same thing. --- src/backend/bootstrap/bootstrap.c | 2 +- src/backend/catalog/heap.c | 3 ++- src/backend/catalog/index.c | 22 ++++++++++++++++++---- src/backend/catalog/toasting.c | 3 ++- src/backend/commands/cluster.c | 7 ++++--- src/backend/commands/indexcmds.c | 1 + src/include/catalog/index.h | 4 +++- 7 files changed, 31 insertions(+), 11 deletions(-) diff --git a/src/backend/bootstrap/bootstrap.c b/src/backend/bootstrap/bootstrap.c index 68a42de0889..1c8226c6d67 100644 --- a/src/backend/bootstrap/bootstrap.c +++ b/src/backend/bootstrap/bootstrap.c @@ -1181,7 +1181,7 @@ build_indices(void) heap = table_open(ILHead->il_heap, NoLock); ind = index_open(ILHead->il_ind, NoLock); - index_build(heap, ind, ILHead->il_info, false, false); + index_build(heap, ind, ILHead->il_info, false, false, false); index_close(ind, NoLock); table_close(heap, NoLock); diff --git a/src/backend/catalog/heap.c b/src/backend/catalog/heap.c index 5748aa9a1a9..ae6b7cda3dd 100644 --- a/src/backend/catalog/heap.c +++ b/src/backend/catalog/heap.c @@ -3570,7 +3570,8 @@ RelationTruncateIndexes(Relation heapRelation) /* Initialize the index and rebuild */ /* Note: we do not need to re-establish pkey setting */ - index_build(heapRelation, currentIndex, indexInfo, true, false); + index_build(heapRelation, currentIndex, indexInfo, true, false, + true); /* We're done with this index */ index_close(currentIndex, NoLock); diff --git a/src/backend/catalog/index.c b/src/backend/catalog/index.c index de7182a85a9..cfd33f73f48 100644 --- a/src/backend/catalog/index.c +++ b/src/backend/catalog/index.c @@ -715,6 +715,9 @@ UpdateIndexRelation(Oid indexoid, * already exists. * INDEX_CREATE_PARTITIONED: * create a partitioned index (table must be partitioned) + * INDEX_CREATE_REPORT_PROGRESS: + * update the backend's progress information during index build. + * constr_flags: flags passed to index_constraint_create * (only if INDEX_CREATE_ADD_CONSTRAINT is set) * allow_system_table_mods: allow table to be a system catalog @@ -760,6 +763,7 @@ index_create(Relation heapRelation, bool invalid = (flags & INDEX_CREATE_INVALID) != 0; bool concurrent = (flags & INDEX_CREATE_CONCURRENT) != 0; bool partitioned = (flags & INDEX_CREATE_PARTITIONED) != 0; + bool progress = (flags & INDEX_CREATE_REPORT_PROGRESS) != 0; char relkind; TransactionId relfrozenxid; MultiXactId relminmxid; @@ -1276,7 +1280,8 @@ index_create(Relation heapRelation, } else { - index_build(heapRelation, indexRelation, indexInfo, false, true); + index_build(heapRelation, indexRelation, indexInfo, false, true, + progress); } /* @@ -1438,6 +1443,12 @@ index_create_copy(Relation heapRelation, bool concurrently, stattargets[i].isnull = isnull; } + /* + * Note: The current callers do not need INDEX_CREATE_REPORT_PROGRESS.

Second, REPACK (CONCURRENTLY) should not set PROGRESS_REPACK_PHASE to PROGRESS_REPACK_PHASE_FINAL_CLEANUP in rebuild_relation() because it calls finish_heap_swap() anyway (via rebuild_relation_finish_concurrent()), which does the same thing. --- src/backend/bootstrap/bootstrap.c | 2 +- src/backend/catalog/heap.c | 3 ++- src/backend/catalog/index.c | 22 ++++++++++++++++++---- src/backend/catalog/toasting.c | 3 ++- src/backend/commands/cluster.c | 7 ++++--- src/backend/commands/indexcmds.c | 1 + src/include/catalog/index.h | 4 +++- 7 files changed, 31 insertions(+), 11 deletions(-) diff --git a/src/backend/bootstrap/bootstrap.c b/src/backend/bootstrap/bootstrap.c index 68a42de0889..1c8226c6d67 100644 --- a/src/backend/bootstrap/bootstrap.c +++ b/src/backend/bootstrap/bootstrap.c @@ -1181,7 +1181,7 @@ build_indices(void) heap = table_open(ILHead->il_heap, NoLock); ind = index_open(ILHead->il_ind, NoLock); - index_build(heap, ind, ILHead->il_info, false, false); + index_build(heap, ind, ILHead->il_info, false, false, false); index_close(ind, NoLock); table_close(heap, NoLock); diff --git a/src/backend/catalog/heap.c b/src/backend/catalog/heap.c index 5748aa9a1a9..ae6b7cda3dd 100644 --- a/src/backend/catalog/heap.c +++ b/src/backend/catalog/heap.c @@ -3570,7 +3570,8 @@ RelationTruncateIndexes(Relation heapRelation) /* Initialize the index and rebuild */ /* Note: we do not need to re-establish pkey setting */ - index_build(heapRelation, currentIndex, indexInfo, true, false); + index_build(heapRelation, currentIndex, indexInfo, true, false, + true); /* We're done with this index */ index_close(currentIndex, NoLock); diff --git a/src/backend/catalog/index.c b/src/backend/catalog/index.c index 98d38dc5229..1d28202de34 100644 --- a/src/backend/catalog/index.c +++ b/src/backend/catalog/index.c @@ -715,6 +715,9 @@ UpdateIndexRelation(Oid indexoid, * already exists. * INDEX_CREATE_PARTITIONED: * create a partitioned index (table must be partitioned) + * INDEX_CREATE_REPORT_PROGRESS: + * update the backend's progress information during index build. + * constr_flags: flags passed to index_constraint_create * (only if INDEX_CREATE_ADD_CONSTRAINT is set) * allow_system_table_mods: allow table to be a system catalog @@ -760,6 +763,7 @@ index_create(Relation heapRelation, bool invalid = (flags & INDEX_CREATE_INVALID) != 0; bool concurrent = (flags & INDEX_CREATE_CONCURRENT) != 0; bool partitioned = (flags & INDEX_CREATE_PARTITIONED) != 0; + bool progress = (flags & INDEX_CREATE_REPORT_PROGRESS) != 0; char relkind; TransactionId relfrozenxid; MultiXactId relminmxid; @@ -1276,7 +1280,8 @@ index_create(Relation heapRelation, } else { - index_build(heapRelation, indexRelation, indexInfo, false, true); + index_build(heapRelation, indexRelation, indexInfo, false, true, + progress); } /* @@ -1455,6 +1460,12 @@ index_create_copy(Relation heapRelation, Oid oldIndexId, Oid tablespaceOid, stattargets[i].isnull = isnull; } + /* + * Note: The current callers do not need INDEX_CREATE_REPORT_PROGRESS.

Second, REPACK (CONCURRENTLY) should not set PROGRESS_REPACK_PHASE to PROGRESS_REPACK_PHASE_FINAL_CLEANUP in rebuild_relation() because it calls finish_heap_swap() anyway (via rebuild_relation_finish_concurrent()), which does the same thing. --- src/backend/bootstrap/bootstrap.c | 2 +- src/backend/catalog/heap.c | 3 ++- src/backend/catalog/index.c | 22 ++++++++++++++++++---- src/backend/catalog/toasting.c | 3 ++- src/backend/commands/cluster.c | 7 ++++--- src/backend/commands/indexcmds.c | 1 + src/include/catalog/index.h | 4 +++- 7 files changed, 31 insertions(+), 11 deletions(-) diff --git a/src/backend/bootstrap/bootstrap.c b/src/backend/bootstrap/bootstrap.c index 68a42de0889..1c8226c6d67 100644 --- a/src/backend/bootstrap/bootstrap.c +++ b/src/backend/bootstrap/bootstrap.c @@ -1181,7 +1181,7 @@ build_indices(void) heap = table_open(ILHead->il_heap, NoLock); ind = index_open(ILHead->il_ind, NoLock); - index_build(heap, ind, ILHead->il_info, false, false); + index_build(heap, ind, ILHead->il_info, false, false, false); index_close(ind, NoLock); table_close(heap, NoLock); diff --git a/src/backend/catalog/heap.c b/src/backend/catalog/heap.c index 5748aa9a1a9..ae6b7cda3dd 100644 --- a/src/backend/catalog/heap.c +++ b/src/backend/catalog/heap.c @@ -3570,7 +3570,8 @@ RelationTruncateIndexes(Relation heapRelation) /* Initialize the index and rebuild */ /* Note: we do not need to re-establish pkey setting */ - index_build(heapRelation, currentIndex, indexInfo, true, false); + index_build(heapRelation, currentIndex, indexInfo, true, false, + true); /* We're done with this index */ index_close(currentIndex, NoLock); diff --git a/src/backend/catalog/index.c b/src/backend/catalog/index.c index 98d38dc5229..1d28202de34 100644 --- a/src/backend/catalog/index.c +++ b/src/backend/catalog/index.c @@ -715,6 +715,9 @@ UpdateIndexRelation(Oid indexoid, * already exists. * INDEX_CREATE_PARTITIONED: * create a partitioned index (table must be partitioned) + * INDEX_CREATE_REPORT_PROGRESS: + * update the backend's progress information during index build. + * constr_flags: flags passed to index_constraint_create * (only if INDEX_CREATE_ADD_CONSTRAINT is set) * allow_system_table_mods: allow table to be a system catalog @@ -760,6 +763,7 @@ index_create(Relation heapRelation, bool invalid = (flags & INDEX_CREATE_INVALID) != 0; bool concurrent = (flags & INDEX_CREATE_CONCURRENT) != 0; bool partitioned = (flags & INDEX_CREATE_PARTITIONED) != 0; + bool progress = (flags & INDEX_CREATE_REPORT_PROGRESS) != 0; char relkind; TransactionId relfrozenxid; MultiXactId relminmxid; @@ -1276,7 +1280,8 @@ index_create(Relation heapRelation, } else { - index_build(heapRelation, indexRelation, indexInfo, false, true); + index_build(heapRelation, indexRelation, indexInfo, false, true, + progress); } /* @@ -1455,6 +1460,12 @@ index_create_copy(Relation heapRelation, Oid oldIndexId, Oid tablespaceOid, stattargets[i].isnull = isnull; } + /* + * Note: The current callers do not need INDEX_CREATE_REPORT_PROGRESS.

Second, REPACK (CONCURRENTLY) should not set PROGRESS_REPACK_PHASE to PROGRESS_REPACK_PHASE_FINAL_CLEANUP in rebuild_relation() because it calls finish_heap_swap() anyway (via rebuild_relation_finish_concurrent()), which does the same thing. --- src/backend/bootstrap/bootstrap.c | 2 +- src/backend/catalog/heap.c | 3 ++- src/backend/catalog/index.c | 22 ++++++++++++++++++---- src/backend/catalog/toasting.c | 3 ++- src/backend/commands/cluster.c | 7 ++++--- src/backend/commands/indexcmds.c | 1 + src/include/catalog/index.h | 4 +++- 7 files changed, 31 insertions(+), 11 deletions(-) diff --git a/src/backend/bootstrap/bootstrap.c b/src/backend/bootstrap/bootstrap.c index 68a42de0889..1c8226c6d67 100644 --- a/src/backend/bootstrap/bootstrap.c +++ b/src/backend/bootstrap/bootstrap.c @@ -1181,7 +1181,7 @@ build_indices(void) heap = table_open(ILHead->il_heap, NoLock); ind = index_open(ILHead->il_ind, NoLock); - index_build(heap, ind, ILHead->il_info, false, false); + index_build(heap, ind, ILHead->il_info, false, false, false); index_close(ind, NoLock); table_close(heap, NoLock); diff --git a/src/backend/catalog/heap.c b/src/backend/catalog/heap.c index 5748aa9a1a9..ae6b7cda3dd 100644 --- a/src/backend/catalog/heap.c +++ b/src/backend/catalog/heap.c @@ -3570,7 +3570,8 @@ RelationTruncateIndexes(Relation heapRelation) /* Initialize the index and rebuild */ /* Note: we do not need to re-establish pkey setting */ - index_build(heapRelation, currentIndex, indexInfo, true, false); + index_build(heapRelation, currentIndex, indexInfo, true, false, + true); /* We're done with this index */ index_close(currentIndex, NoLock); diff --git a/src/backend/catalog/index.c b/src/backend/catalog/index.c index 544dd0d6e3d..13284f1d708 100644 --- a/src/backend/catalog/index.c +++ b/src/backend/catalog/index.c @@ -715,6 +715,9 @@ UpdateIndexRelation(Oid indexoid, * already exists. * INDEX_CREATE_PARTITIONED: * create a partitioned index (table must be partitioned) + * INDEX_CREATE_REPORT_PROGRESS: + * update the backend's progress information during index build. + * constr_flags: flags passed to index_constraint_create * (only if INDEX_CREATE_ADD_CONSTRAINT is set) * allow_system_table_mods: allow table to be a system catalog @@ -760,6 +763,7 @@ index_create(Relation heapRelation, bool invalid = (flags & INDEX_CREATE_INVALID) != 0; bool concurrent = (flags & INDEX_CREATE_CONCURRENT) != 0; bool partitioned = (flags & INDEX_CREATE_PARTITIONED) != 0; + bool progress = (flags & INDEX_CREATE_REPORT_PROGRESS) != 0; char relkind; TransactionId relfrozenxid; MultiXactId relminmxid; @@ -1276,7 +1280,8 @@ index_create(Relation heapRelation, } else { - index_build(heapRelation, indexRelation, indexInfo, false, true); + index_build(heapRelation, indexRelation, indexInfo, false, true, + progress); } /* @@ -1455,6 +1460,12 @@ index_create_copy(Relation heapRelation, Oid oldIndexId, Oid tablespaceOid, stattargets[i].isnull = isnull; } + /* + * Note: The current callers do not need INDEX_CREATE_REPORT_PROGRESS.

Second, REPACK (CONCURRENTLY) should not set PROGRESS_REPACK_PHASE to PROGRESS_REPACK_PHASE_FINAL_CLEANUP in rebuild_relation() because it calls finish_heap_swap() anyway (via rebuild_relation_finish_concurrent()), which does the same thing. --- src/backend/bootstrap/bootstrap.c | 2 +- src/backend/catalog/heap.c | 3 ++- src/backend/catalog/index.c | 22 ++++++++++++++++++---- src/backend/catalog/toasting.c | 3 ++- src/backend/commands/cluster.c | 7 ++++--- src/backend/commands/indexcmds.c | 1 + src/include/catalog/index.h | 4 +++- 7 files changed, 31 insertions(+), 11 deletions(-) diff --git a/src/backend/bootstrap/bootstrap.c b/src/backend/bootstrap/bootstrap.c index 68a42de0889..1c8226c6d67 100644 --- a/src/backend/bootstrap/bootstrap.c +++ b/src/backend/bootstrap/bootstrap.c @@ -1181,7 +1181,7 @@ build_indices(void) heap = table_open(ILHead->il_heap, NoLock); ind = index_open(ILHead->il_ind, NoLock); - index_build(heap, ind, ILHead->il_info, false, false); + index_build(heap, ind, ILHead->il_info, false, false, false); index_close(ind, NoLock); table_close(heap, NoLock); diff --git a/src/backend/catalog/heap.c b/src/backend/catalog/heap.c index 5748aa9a1a9..ae6b7cda3dd 100644 --- a/src/backend/catalog/heap.c +++ b/src/backend/catalog/heap.c @@ -3570,7 +3570,8 @@ RelationTruncateIndexes(Relation heapRelation) /* Initialize the index and rebuild */ /* Note: we do not need to re-establish pkey setting */ - index_build(heapRelation, currentIndex, indexInfo, true, false); + index_build(heapRelation, currentIndex, indexInfo, true, false, + true); /* We're done with this index */ index_close(currentIndex, NoLock); diff --git a/src/backend/catalog/index.c b/src/backend/catalog/index.c index de7182a85a9..cfd33f73f48 100644 --- a/src/backend/catalog/index.c +++ b/src/backend/catalog/index.c @@ -715,6 +715,9 @@ UpdateIndexRelation(Oid indexoid, * already exists. * INDEX_CREATE_PARTITIONED: * create a partitioned index (table must be partitioned) + * INDEX_CREATE_REPORT_PROGRESS: + * update the backend's progress information during index build. + * constr_flags: flags passed to index_constraint_create * (only if INDEX_CREATE_ADD_CONSTRAINT is set) * allow_system_table_mods: allow table to be a system catalog @@ -760,6 +763,7 @@ index_create(Relation heapRelation, bool invalid = (flags & INDEX_CREATE_INVALID) != 0; bool concurrent = (flags & INDEX_CREATE_CONCURRENT) != 0; bool partitioned = (flags & INDEX_CREATE_PARTITIONED) != 0; + bool progress = (flags & INDEX_CREATE_REPORT_PROGRESS) != 0; char relkind; TransactionId relfrozenxid; MultiXactId relminmxid; @@ -1276,7 +1280,8 @@ index_create(Relation heapRelation, } else { - index_build(heapRelation, indexRelation, indexInfo, false, true); + index_build(heapRelation, indexRelation, indexInfo, false, true, + progress); } /* @@ -1438,6 +1443,12 @@ index_create_copy(Relation heapRelation, bool concurrently, stattargets[i].isnull = isnull; } + /* + * Note: The current callers do not need INDEX_CREATE_REPORT_PROGRESS.

Second, REPACK (CONCURRENTLY) should not set PROGRESS_REPACK_PHASE to PROGRESS_REPACK_PHASE_FINAL_CLEANUP in rebuild_relation() because it calls finish_heap_swap() anyway (via rebuild_relation_finish_concurrent()), which does the same thing. --- src/backend/bootstrap/bootstrap.c | 2 +- src/backend/catalog/heap.c | 3 ++- src/backend/catalog/index.c | 22 ++++++++++++++++++---- src/backend/catalog/toasting.c | 3 ++- src/backend/commands/cluster.c | 7 ++++--- src/backend/commands/indexcmds.c | 1 + src/include/catalog/index.h | 4 +++- 7 files changed, 31 insertions(+), 11 deletions(-) diff --git a/src/backend/bootstrap/bootstrap.c b/src/backend/bootstrap/bootstrap.c index 68a42de0889..1c8226c6d67 100644 --- a/src/backend/bootstrap/bootstrap.c +++ b/src/backend/bootstrap/bootstrap.c @@ -1181,7 +1181,7 @@ build_indices(void) heap = table_open(ILHead->il_heap, NoLock); ind = index_open(ILHead->il_ind, NoLock); - index_build(heap, ind, ILHead->il_info, false, false); + index_build(heap, ind, ILHead->il_info, false, false, false); index_close(ind, NoLock); table_close(heap, NoLock); diff --git a/src/backend/catalog/heap.c b/src/backend/catalog/heap.c index 5748aa9a1a9..ae6b7cda3dd 100644 --- a/src/backend/catalog/heap.c +++ b/src/backend/catalog/heap.c @@ -3570,7 +3570,8 @@ RelationTruncateIndexes(Relation heapRelation) /* Initialize the index and rebuild */ /* Note: we do not need to re-establish pkey setting */ - index_build(heapRelation, currentIndex, indexInfo, true, false); + index_build(heapRelation, currentIndex, indexInfo, true, false, + true); /* We're done with this index */ index_close(currentIndex, NoLock); diff --git a/src/backend/catalog/index.c b/src/backend/catalog/index.c index de7182a85a9..cfd33f73f48 100644 --- a/src/backend/catalog/index.c +++ b/src/backend/catalog/index.c @@ -715,6 +715,9 @@ UpdateIndexRelation(Oid indexoid, * already exists. * INDEX_CREATE_PARTITIONED: * create a partitioned index (table must be partitioned) + * INDEX_CREATE_REPORT_PROGRESS: + * update the backend's progress information during index build. + * constr_flags: flags passed to index_constraint_create * (only if INDEX_CREATE_ADD_CONSTRAINT is set) * allow_system_table_mods: allow table to be a system catalog @@ -760,6 +763,7 @@ index_create(Relation heapRelation, bool invalid = (flags & INDEX_CREATE_INVALID) != 0; bool concurrent = (flags & INDEX_CREATE_CONCURRENT) != 0; bool partitioned = (flags & INDEX_CREATE_PARTITIONED) != 0; + bool progress = (flags & INDEX_CREATE_REPORT_PROGRESS) != 0; char relkind; TransactionId relfrozenxid; MultiXactId relminmxid; @@ -1276,7 +1280,8 @@ index_create(Relation heapRelation, } else { - index_build(heapRelation, indexRelation, indexInfo, false, true); + index_build(heapRelation, indexRelation, indexInfo, false, true, + progress); } /* @@ -1438,6 +1443,12 @@ index_create_copy(Relation heapRelation, bool concurrently, stattargets[i].isnull = isnull; } + /* + * Note: The current callers do not need INDEX_CREATE_REPORT_PROGRESS.

Second, REPACK (CONCURRENTLY) should not set PROGRESS_REPACK_PHASE to PROGRESS_REPACK_PHASE_FINAL_CLEANUP in rebuild_relation() because it calls finish_heap_swap() anyway (via rebuild_relation_finish_concurrent()), which does the same thing. --- src/backend/bootstrap/bootstrap.c | 2 +- src/backend/catalog/heap.c | 3 ++- src/backend/catalog/index.c | 22 ++++++++++++++++++---- src/backend/catalog/toasting.c | 3 ++- src/backend/commands/cluster.c | 7 ++++--- src/backend/commands/indexcmds.c | 1 + src/include/catalog/index.h | 4 +++- 7 files changed, 31 insertions(+), 11 deletions(-) diff --git a/src/backend/bootstrap/bootstrap.c b/src/backend/bootstrap/bootstrap.c index 68a42de0889..1c8226c6d67 100644 --- a/src/backend/bootstrap/bootstrap.c +++ b/src/backend/bootstrap/bootstrap.c @@ -1181,7 +1181,7 @@ build_indices(void) heap = table_open(ILHead->il_heap, NoLock); ind = index_open(ILHead->il_ind, NoLock); - index_build(heap, ind, ILHead->il_info, false, false); + index_build(heap, ind, ILHead->il_info, false, false, false); index_close(ind, NoLock); table_close(heap, NoLock); diff --git a/src/backend/catalog/heap.c b/src/backend/catalog/heap.c index 5748aa9a1a9..ae6b7cda3dd 100644 --- a/src/backend/catalog/heap.c +++ b/src/backend/catalog/heap.c @@ -3570,7 +3570,8 @@ RelationTruncateIndexes(Relation heapRelation) /* Initialize the index and rebuild */ /* Note: we do not need to re-establish pkey setting */ - index_build(heapRelation, currentIndex, indexInfo, true, false); + index_build(heapRelation, currentIndex, indexInfo, true, false, + true); /* We're done with this index */ index_close(currentIndex, NoLock); diff --git a/src/backend/catalog/index.c b/src/backend/catalog/index.c index de7182a85a9..cfd33f73f48 100644 --- a/src/backend/catalog/index.c +++ b/src/backend/catalog/index.c @@ -715,6 +715,9 @@ UpdateIndexRelation(Oid indexoid, * already exists. * INDEX_CREATE_PARTITIONED: * create a partitioned index (table must be partitioned) + * INDEX_CREATE_REPORT_PROGRESS: + * update the backend's progress information during index build. + * constr_flags: flags passed to index_constraint_create * (only if INDEX_CREATE_ADD_CONSTRAINT is set) * allow_system_table_mods: allow table to be a system catalog @@ -760,6 +763,7 @@ index_create(Relation heapRelation, bool invalid = (flags & INDEX_CREATE_INVALID) != 0; bool concurrent = (flags & INDEX_CREATE_CONCURRENT) != 0; bool partitioned = (flags & INDEX_CREATE_PARTITIONED) != 0; + bool progress = (flags & INDEX_CREATE_REPORT_PROGRESS) != 0; char relkind; TransactionId relfrozenxid; MultiXactId relminmxid; @@ -1276,7 +1280,8 @@ index_create(Relation heapRelation, } else { - index_build(heapRelation, indexRelation, indexInfo, false, true); + index_build(heapRelation, indexRelation, indexInfo, false, true, + progress); } /* @@ -1438,6 +1443,12 @@ index_create_copy(Relation heapRelation, bool concurrently, stattargets[i].isnull = isnull; } + /* + * Note: The current callers do not need INDEX_CREATE_REPORT_PROGRESS.

Second, REPACK (CONCURRENTLY) should not set PROGRESS_REPACK_PHASE to PROGRESS_REPACK_PHASE_FINAL_CLEANUP in rebuild_relation() because it calls finish_heap_swap() anyway (via rebuild_relation_finish_concurrent()), which does the same thing. --- src/backend/bootstrap/bootstrap.c | 2 +- src/backend/catalog/heap.c | 3 ++- src/backend/catalog/index.c | 22 ++++++++++++++++++---- src/backend/catalog/toasting.c | 3 ++- src/backend/commands/cluster.c | 7 ++++--- src/backend/commands/indexcmds.c | 1 + src/include/catalog/index.h | 4 +++- 7 files changed, 31 insertions(+), 11 deletions(-) diff --git a/src/backend/bootstrap/bootstrap.c b/src/backend/bootstrap/bootstrap.c index 68a42de0889..1c8226c6d67 100644 --- a/src/backend/bootstrap/bootstrap.c +++ b/src/backend/bootstrap/bootstrap.c @@ -1181,7 +1181,7 @@ build_indices(void) heap = table_open(ILHead->il_heap, NoLock); ind = index_open(ILHead->il_ind, NoLock); - index_build(heap, ind, ILHead->il_info, false, false); + index_build(heap, ind, ILHead->il_info, false, false, false); index_close(ind, NoLock); table_close(heap, NoLock); diff --git a/src/backend/catalog/heap.c b/src/backend/catalog/heap.c index 5748aa9a1a9..ae6b7cda3dd 100644 --- a/src/backend/catalog/heap.c +++ b/src/backend/catalog/heap.c @@ -3570,7 +3570,8 @@ RelationTruncateIndexes(Relation heapRelation) /* Initialize the index and rebuild */ /* Note: we do not need to re-establish pkey setting */ - index_build(heapRelation, currentIndex, indexInfo, true, false); + index_build(heapRelation, currentIndex, indexInfo, true, false, + true); /* We're done with this index */ index_close(currentIndex, NoLock); diff --git a/src/backend/catalog/index.c b/src/backend/catalog/index.c index de7182a85a9..cfd33f73f48 100644 --- a/src/backend/catalog/index.c +++ b/src/backend/catalog/index.c @@ -715,6 +715,9 @@ UpdateIndexRelation(Oid indexoid, * already exists. * INDEX_CREATE_PARTITIONED: * create a partitioned index (table must be partitioned) + * INDEX_CREATE_REPORT_PROGRESS: + * update the backend's progress information during index build. + * constr_flags: flags passed to index_constraint_create * (only if INDEX_CREATE_ADD_CONSTRAINT is set) * allow_system_table_mods: allow table to be a system catalog @@ -760,6 +763,7 @@ index_create(Relation heapRelation, bool invalid = (flags & INDEX_CREATE_INVALID) != 0; bool concurrent = (flags & INDEX_CREATE_CONCURRENT) != 0; bool partitioned = (flags & INDEX_CREATE_PARTITIONED) != 0; + bool progress = (flags & INDEX_CREATE_REPORT_PROGRESS) != 0; char relkind; TransactionId relfrozenxid; MultiXactId relminmxid; @@ -1276,7 +1280,8 @@ index_create(Relation heapRelation, } else { - index_build(heapRelation, indexRelation, indexInfo, false, true); + index_build(heapRelation, indexRelation, indexInfo, false, true, + progress); } /* @@ -1438,6 +1443,12 @@ index_create_copy(Relation heapRelation, bool concurrently, stattargets[i].isnull = isnull; } + /* + * Note: The current callers do not need INDEX_CREATE_REPORT_PROGRESS.

Second, REPACK (CONCURRENTLY) should not set PROGRESS_REPACK_PHASE to PROGRESS_REPACK_PHASE_FINAL_CLEANUP in rebuild_relation() because it calls finish_heap_swap() anyway (via rebuild_relation_finish_concurrent()), which does the same thing. --- src/backend/bootstrap/bootstrap.c | 2 +- src/backend/catalog/heap.c | 3 ++- src/backend/catalog/index.c | 22 ++++++++++++++++++---- src/backend/catalog/toasting.c | 3 ++- src/backend/commands/cluster.c | 7 ++++--- src/backend/commands/indexcmds.c | 1 + src/include/catalog/index.h | 4 +++- 7 files changed, 31 insertions(+), 11 deletions(-) diff --git a/src/backend/bootstrap/bootstrap.c b/src/backend/bootstrap/bootstrap.c index 68a42de0889..1c8226c6d67 100644 --- a/src/backend/bootstrap/bootstrap.c +++ b/src/backend/bootstrap/bootstrap.c @@ -1181,7 +1181,7 @@ build_indices(void) heap = table_open(ILHead->il_heap, NoLock); ind = index_open(ILHead->il_ind, NoLock); - index_build(heap, ind, ILHead->il_info, false, false); + index_build(heap, ind, ILHead->il_info, false, false, false); index_close(ind, NoLock); table_close(heap, NoLock); diff --git a/src/backend/catalog/heap.c b/src/backend/catalog/heap.c index 5748aa9a1a9..ae6b7cda3dd 100644 --- a/src/backend/catalog/heap.c +++ b/src/backend/catalog/heap.c @@ -3570,7 +3570,8 @@ RelationTruncateIndexes(Relation heapRelation) /* Initialize the index and rebuild */ /* Note: we do not need to re-establish pkey setting */ - index_build(heapRelation, currentIndex, indexInfo, true, false); + index_build(heapRelation, currentIndex, indexInfo, true, false, + true); /* We're done with this index */ index_close(currentIndex, NoLock); diff --git a/src/backend/catalog/index.c b/src/backend/catalog/index.c index 98d38dc5229..1d28202de34 100644 --- a/src/backend/catalog/index.c +++ b/src/backend/catalog/index.c @@ -715,6 +715,9 @@ UpdateIndexRelation(Oid indexoid, * already exists. * INDEX_CREATE_PARTITIONED: * create a partitioned index (table must be partitioned) + * INDEX_CREATE_REPORT_PROGRESS: + * update the backend's progress information during index build. + * constr_flags: flags passed to index_constraint_create * (only if INDEX_CREATE_ADD_CONSTRAINT is set) * allow_system_table_mods: allow table to be a system catalog @@ -760,6 +763,7 @@ index_create(Relation heapRelation, bool invalid = (flags & INDEX_CREATE_INVALID) != 0; bool concurrent = (flags & INDEX_CREATE_CONCURRENT) != 0; bool partitioned = (flags & INDEX_CREATE_PARTITIONED) != 0; + bool progress = (flags & INDEX_CREATE_REPORT_PROGRESS) != 0; char relkind; TransactionId relfrozenxid; MultiXactId relminmxid; @@ -1276,7 +1280,8 @@ index_create(Relation heapRelation, } else { - index_build(heapRelation, indexRelation, indexInfo, false, true); + index_build(heapRelation, indexRelation, indexInfo, false, true, + progress); } /* @@ -1455,6 +1460,12 @@ index_create_copy(Relation heapRelation, Oid oldIndexId, Oid tablespaceOid, stattargets[i].isnull = isnull; } + /* + * Note: The current callers do not need INDEX_CREATE_REPORT_PROGRESS.

Second, REPACK (CONCURRENTLY) should not set PROGRESS_REPACK_PHASE to PROGRESS_REPACK_PHASE_FINAL_CLEANUP in rebuild_relation() because it calls finish_heap_swap() anyway (via rebuild_relation_finish_concurrent()), which does the same thing. --- src/backend/bootstrap/bootstrap.c | 2 +- src/backend/catalog/heap.c | 3 ++- src/backend/catalog/index.c | 22 ++++++++++++++++++---- src/backend/catalog/toasting.c | 3 ++- src/backend/commands/cluster.c | 7 ++++--- src/backend/commands/indexcmds.c | 1 + src/include/catalog/index.h | 4 +++- 7 files changed, 31 insertions(+), 11 deletions(-) diff --git a/src/backend/bootstrap/bootstrap.c b/src/backend/bootstrap/bootstrap.c index 17118f2fe76..cb06c52c1d4 100644 --- a/src/backend/bootstrap/bootstrap.c +++ b/src/backend/bootstrap/bootstrap.c @@ -1180,7 +1180,7 @@ build_indices(void) heap = table_open(ILHead->il_heap, NoLock); ind = index_open(ILHead->il_ind, NoLock); - index_build(heap, ind, ILHead->il_info, false, false); + index_build(heap, ind, ILHead->il_info, false, false, false); index_close(ind, NoLock); table_close(heap, NoLock); diff --git a/src/backend/catalog/heap.c b/src/backend/catalog/heap.c index 5748aa9a1a9..ae6b7cda3dd 100644 --- a/src/backend/catalog/heap.c +++ b/src/backend/catalog/heap.c @@ -3570,7 +3570,8 @@ RelationTruncateIndexes(Relation heapRelation) /* Initialize the index and rebuild */ /* Note: we do not need to re-establish pkey setting */ - index_build(heapRelation, currentIndex, indexInfo, true, false); + index_build(heapRelation, currentIndex, indexInfo, true, false, + true); /* We're done with this index */ index_close(currentIndex, NoLock); diff --git a/src/backend/catalog/index.c b/src/backend/catalog/index.c index b1e05d56a1e..89aad2f7b77 100644 --- a/src/backend/catalog/index.c +++ b/src/backend/catalog/index.c @@ -714,6 +714,9 @@ UpdateIndexRelation(Oid indexoid, * already exists. * INDEX_CREATE_PARTITIONED: * create a partitioned index (table must be partitioned) + * INDEX_CREATE_REPORT_PROGRESS: + * update the backend's progress information during index build. + * constr_flags: flags passed to index_constraint_create * (only if INDEX_CREATE_ADD_CONSTRAINT is set) * allow_system_table_mods: allow table to be a system catalog @@ -759,6 +762,7 @@ index_create(Relation heapRelation, bool invalid = (flags & INDEX_CREATE_INVALID) != 0; bool concurrent = (flags & INDEX_CREATE_CONCURRENT) != 0; bool partitioned = (flags & INDEX_CREATE_PARTITIONED) != 0; + bool progress = (flags & INDEX_CREATE_REPORT_PROGRESS) != 0; char relkind; TransactionId relfrozenxid; MultiXactId relminmxid; @@ -1275,7 +1279,8 @@ index_create(Relation heapRelation, } else { - index_build(heapRelation, indexRelation, indexInfo, false, true); + index_build(heapRelation, indexRelation, indexInfo, false, true, + progress); } /* @@ -1454,6 +1459,12 @@ index_create_copy(Relation heapRelation, Oid oldIndexId, Oid tablespaceOid, stattargets[i].isnull = isnull; } + /* + * Note: The current callers do not need INDEX_CREATE_REPORT_PROGRESS.

Second, REPACK (CONCURRENTLY) should not set PROGRESS_REPACK_PHASE to PROGRESS_REPACK_PHASE_FINAL_CLEANUP in rebuild_relation() because it calls finish_heap_swap() anyway (via rebuild_relation_finish_concurrent()), which does the same thing. --- src/backend/bootstrap/bootstrap.c | 2 +- src/backend/catalog/heap.c | 3 ++- src/backend/catalog/index.c | 22 ++++++++++++++++++---- src/backend/catalog/toasting.c | 3 ++- src/backend/commands/cluster.c | 7 ++++--- src/backend/commands/indexcmds.c | 1 + src/include/catalog/index.h | 4 +++- 7 files changed, 31 insertions(+), 11 deletions(-) diff --git a/src/backend/bootstrap/bootstrap.c b/src/backend/bootstrap/bootstrap.c index 17118f2fe76..cb06c52c1d4 100644 --- a/src/backend/bootstrap/bootstrap.c +++ b/src/backend/bootstrap/bootstrap.c @@ -1180,7 +1180,7 @@ build_indices(void) heap = table_open(ILHead->il_heap, NoLock); ind = index_open(ILHead->il_ind, NoLock); - index_build(heap, ind, ILHead->il_info, false, false); + index_build(heap, ind, ILHead->il_info, false, false, false); index_close(ind, NoLock); table_close(heap, NoLock); diff --git a/src/backend/catalog/heap.c b/src/backend/catalog/heap.c index 5748aa9a1a9..ae6b7cda3dd 100644 --- a/src/backend/catalog/heap.c +++ b/src/backend/catalog/heap.c @@ -3570,7 +3570,8 @@ RelationTruncateIndexes(Relation heapRelation) /* Initialize the index and rebuild */ /* Note: we do not need to re-establish pkey setting */ - index_build(heapRelation, currentIndex, indexInfo, true, false); + index_build(heapRelation, currentIndex, indexInfo, true, false, + true); /* We're done with this index */ index_close(currentIndex, NoLock); diff --git a/src/backend/catalog/index.c b/src/backend/catalog/index.c index b1e05d56a1e..89aad2f7b77 100644 --- a/src/backend/catalog/index.c +++ b/src/backend/catalog/index.c @@ -714,6 +714,9 @@ UpdateIndexRelation(Oid indexoid, * already exists. * INDEX_CREATE_PARTITIONED: * create a partitioned index (table must be partitioned) + * INDEX_CREATE_REPORT_PROGRESS: + * update the backend's progress information during index build. + * constr_flags: flags passed to index_constraint_create * (only if INDEX_CREATE_ADD_CONSTRAINT is set) * allow_system_table_mods: allow table to be a system catalog @@ -759,6 +762,7 @@ index_create(Relation heapRelation, bool invalid = (flags & INDEX_CREATE_INVALID) != 0; bool concurrent = (flags & INDEX_CREATE_CONCURRENT) != 0; bool partitioned = (flags & INDEX_CREATE_PARTITIONED) != 0; + bool progress = (flags & INDEX_CREATE_REPORT_PROGRESS) != 0; char relkind; TransactionId relfrozenxid; MultiXactId relminmxid; @@ -1275,7 +1279,8 @@ index_create(Relation heapRelation, } else { - index_build(heapRelation, indexRelation, indexInfo, false, true); + index_build(heapRelation, indexRelation, indexInfo, false, true, + progress); } /* @@ -1454,6 +1459,12 @@ index_create_copy(Relation heapRelation, Oid oldIndexId, Oid tablespaceOid, stattargets[i].isnull = isnull; } + /* + * Note: The current callers do not need INDEX_CREATE_REPORT_PROGRESS.

Second, REPACK (CONCURRENTLY) should not set PROGRESS_REPACK_PHASE to PROGRESS_REPACK_PHASE_FINAL_CLEANUP in rebuild_relation() because it calls finish_heap_swap() anyway (via rebuild_relation_finish_concurrent()), which does the same thing. --- src/backend/bootstrap/bootstrap.c | 2 +- src/backend/catalog/heap.c | 3 ++- src/backend/catalog/index.c | 22 ++++++++++++++++++---- src/backend/catalog/toasting.c | 3 ++- src/backend/commands/cluster.c | 7 ++++--- src/backend/commands/indexcmds.c | 1 + src/include/catalog/index.h | 4 +++- 7 files changed, 31 insertions(+), 11 deletions(-) diff --git a/src/backend/bootstrap/bootstrap.c b/src/backend/bootstrap/bootstrap.c index 68a42de0889..1c8226c6d67 100644 --- a/src/backend/bootstrap/bootstrap.c +++ b/src/backend/bootstrap/bootstrap.c @@ -1181,7 +1181,7 @@ build_indices(void) heap = table_open(ILHead->il_heap, NoLock); ind = index_open(ILHead->il_ind, NoLock); - index_build(heap, ind, ILHead->il_info, false, false); + index_build(heap, ind, ILHead->il_info, false, false, false); index_close(ind, NoLock); table_close(heap, NoLock); diff --git a/src/backend/catalog/heap.c b/src/backend/catalog/heap.c index 5748aa9a1a9..ae6b7cda3dd 100644 --- a/src/backend/catalog/heap.c +++ b/src/backend/catalog/heap.c @@ -3570,7 +3570,8 @@ RelationTruncateIndexes(Relation heapRelation) /* Initialize the index and rebuild */ /* Note: we do not need to re-establish pkey setting */ - index_build(heapRelation, currentIndex, indexInfo, true, false); + index_build(heapRelation, currentIndex, indexInfo, true, false, + true); /* We're done with this index */ index_close(currentIndex, NoLock); diff --git a/src/backend/catalog/index.c b/src/backend/catalog/index.c index 544dd0d6e3d..13284f1d708 100644 --- a/src/backend/catalog/index.c +++ b/src/backend/catalog/index.c @@ -715,6 +715,9 @@ UpdateIndexRelation(Oid indexoid, * already exists. * INDEX_CREATE_PARTITIONED: * create a partitioned index (table must be partitioned) + * INDEX_CREATE_REPORT_PROGRESS: + * update the backend's progress information during index build. + * constr_flags: flags passed to index_constraint_create * (only if INDEX_CREATE_ADD_CONSTRAINT is set) * allow_system_table_mods: allow table to be a system catalog @@ -760,6 +763,7 @@ index_create(Relation heapRelation, bool invalid = (flags & INDEX_CREATE_INVALID) != 0; bool concurrent = (flags & INDEX_CREATE_CONCURRENT) != 0; bool partitioned = (flags & INDEX_CREATE_PARTITIONED) != 0; + bool progress = (flags & INDEX_CREATE_REPORT_PROGRESS) != 0; char relkind; TransactionId relfrozenxid; MultiXactId relminmxid; @@ -1276,7 +1280,8 @@ index_create(Relation heapRelation, } else { - index_build(heapRelation, indexRelation, indexInfo, false, true); + index_build(heapRelation, indexRelation, indexInfo, false, true, + progress); } /* @@ -1455,6 +1460,12 @@ index_create_copy(Relation heapRelation, Oid oldIndexId, Oid tablespaceOid, stattargets[i].isnull = isnull; } + /* + * Note: The current callers do not need INDEX_CREATE_REPORT_PROGRESS.

Second, REPACK (CONCURRENTLY) should not set PROGRESS_REPACK_PHASE to PROGRESS_REPACK_PHASE_FINAL_CLEANUP in rebuild_relation() because it calls finish_heap_swap() anyway (via rebuild_relation_finish_concurrent()), which does the same thing. --- src/backend/bootstrap/bootstrap.c | 2 +- src/backend/catalog/heap.c | 3 ++- src/backend/catalog/index.c | 22 ++++++++++++++++++---- src/backend/catalog/toasting.c | 3 ++- src/backend/commands/cluster.c | 7 ++++--- src/backend/commands/indexcmds.c | 1 + src/include/catalog/index.h | 4 +++- 7 files changed, 31 insertions(+), 11 deletions(-) diff --git a/src/backend/bootstrap/bootstrap.c b/src/backend/bootstrap/bootstrap.c index 68a42de0889..1c8226c6d67 100644 --- a/src/backend/bootstrap/bootstrap.c +++ b/src/backend/bootstrap/bootstrap.c @@ -1181,7 +1181,7 @@ build_indices(void) heap = table_open(ILHead->il_heap, NoLock); ind = index_open(ILHead->il_ind, NoLock); - index_build(heap, ind, ILHead->il_info, false, false); + index_build(heap, ind, ILHead->il_info, false, false, false); index_close(ind, NoLock); table_close(heap, NoLock); diff --git a/src/backend/catalog/heap.c b/src/backend/catalog/heap.c index 5748aa9a1a9..ae6b7cda3dd 100644 --- a/src/backend/catalog/heap.c +++ b/src/backend/catalog/heap.c @@ -3570,7 +3570,8 @@ RelationTruncateIndexes(Relation heapRelation) /* Initialize the index and rebuild */ /* Note: we do not need to re-establish pkey setting */ - index_build(heapRelation, currentIndex, indexInfo, true, false); + index_build(heapRelation, currentIndex, indexInfo, true, false, + true); /* We're done with this index */ index_close(currentIndex, NoLock); diff --git a/src/backend/catalog/index.c b/src/backend/catalog/index.c index 544dd0d6e3d..13284f1d708 100644 --- a/src/backend/catalog/index.c +++ b/src/backend/catalog/index.c @@ -715,6 +715,9 @@ UpdateIndexRelation(Oid indexoid, * already exists. * INDEX_CREATE_PARTITIONED: * create a partitioned index (table must be partitioned) + * INDEX_CREATE_REPORT_PROGRESS: + * update the backend's progress information during index build. + * constr_flags: flags passed to index_constraint_create * (only if INDEX_CREATE_ADD_CONSTRAINT is set) * allow_system_table_mods: allow table to be a system catalog @@ -760,6 +763,7 @@ index_create(Relation heapRelation, bool invalid = (flags & INDEX_CREATE_INVALID) != 0; bool concurrent = (flags & INDEX_CREATE_CONCURRENT) != 0; bool partitioned = (flags & INDEX_CREATE_PARTITIONED) != 0; + bool progress = (flags & INDEX_CREATE_REPORT_PROGRESS) != 0; char relkind; TransactionId relfrozenxid; MultiXactId relminmxid; @@ -1276,7 +1280,8 @@ index_create(Relation heapRelation, } else { - index_build(heapRelation, indexRelation, indexInfo, false, true); + index_build(heapRelation, indexRelation, indexInfo, false, true, + progress); } /* @@ -1455,6 +1460,12 @@ index_create_copy(Relation heapRelation, Oid oldIndexId, Oid tablespaceOid, stattargets[i].isnull = isnull; } + /* + * Note: The current callers do not need INDEX_CREATE_REPORT_PROGRESS.

Second, REPACK (CONCURRENTLY) should not set PROGRESS_REPACK_PHASE to PROGRESS_REPACK_PHASE_FINAL_CLEANUP in rebuild_relation() because it calls finish_heap_swap() anyway (via rebuild_relation_finish_concurrent()), which does the same thing. --- src/backend/bootstrap/bootstrap.c | 2 +- src/backend/catalog/heap.c | 3 ++- src/backend/catalog/index.c | 22 ++++++++++++++++++---- src/backend/catalog/toasting.c | 3 ++- src/backend/commands/cluster.c | 7 ++++--- src/backend/commands/indexcmds.c | 1 + src/include/catalog/index.h | 4 +++- 7 files changed, 31 insertions(+), 11 deletions(-) diff --git a/src/backend/bootstrap/bootstrap.c b/src/backend/bootstrap/bootstrap.c index 17118f2fe76..cb06c52c1d4 100644 --- a/src/backend/bootstrap/bootstrap.c +++ b/src/backend/bootstrap/bootstrap.c @@ -1180,7 +1180,7 @@ build_indices(void) heap = table_open(ILHead->il_heap, NoLock); ind = index_open(ILHead->il_ind, NoLock); - index_build(heap, ind, ILHead->il_info, false, false); + index_build(heap, ind, ILHead->il_info, false, false, false); index_close(ind, NoLock); table_close(heap, NoLock); diff --git a/src/backend/catalog/heap.c b/src/backend/catalog/heap.c index 5748aa9a1a9..ae6b7cda3dd 100644 --- a/src/backend/catalog/heap.c +++ b/src/backend/catalog/heap.c @@ -3570,7 +3570,8 @@ RelationTruncateIndexes(Relation heapRelation) /* Initialize the index and rebuild */ /* Note: we do not need to re-establish pkey setting */ - index_build(heapRelation, currentIndex, indexInfo, true, false); + index_build(heapRelation, currentIndex, indexInfo, true, false, + true); /* We're done with this index */ index_close(currentIndex, NoLock); diff --git a/src/backend/catalog/index.c b/src/backend/catalog/index.c index b1e05d56a1e..89aad2f7b77 100644 --- a/src/backend/catalog/index.c +++ b/src/backend/catalog/index.c @@ -714,6 +714,9 @@ UpdateIndexRelation(Oid indexoid, * already exists. * INDEX_CREATE_PARTITIONED: * create a partitioned index (table must be partitioned) + * INDEX_CREATE_REPORT_PROGRESS: + * update the backend's progress information during index build. + * constr_flags: flags passed to index_constraint_create * (only if INDEX_CREATE_ADD_CONSTRAINT is set) * allow_system_table_mods: allow table to be a system catalog @@ -759,6 +762,7 @@ index_create(Relation heapRelation, bool invalid = (flags & INDEX_CREATE_INVALID) != 0; bool concurrent = (flags & INDEX_CREATE_CONCURRENT) != 0; bool partitioned = (flags & INDEX_CREATE_PARTITIONED) != 0; + bool progress = (flags & INDEX_CREATE_REPORT_PROGRESS) != 0; char relkind; TransactionId relfrozenxid; MultiXactId relminmxid; @@ -1275,7 +1279,8 @@ index_create(Relation heapRelation, } else { - index_build(heapRelation, indexRelation, indexInfo, false, true); + index_build(heapRelation, indexRelation, indexInfo, false, true, + progress); } /* @@ -1454,6 +1459,12 @@ index_create_copy(Relation heapRelation, Oid oldIndexId, Oid tablespaceOid, stattargets[i].isnull = isnull; } + /* + * Note: The current callers do not need INDEX_CREATE_REPORT_PROGRESS.

Second, REPACK (CONCURRENTLY) should not set PROGRESS_REPACK_PHASE to PROGRESS_REPACK_PHASE_FINAL_CLEANUP in rebuild_relation() because it calls finish_heap_swap() anyway (via rebuild_relation_finish_concurrent()), which does the same thing. --- src/backend/bootstrap/bootstrap.c | 2 +- src/backend/catalog/heap.c | 3 ++- src/backend/catalog/index.c | 22 ++++++++++++++++++---- src/backend/catalog/toasting.c | 3 ++- src/backend/commands/cluster.c | 7 ++++--- src/backend/commands/indexcmds.c | 1 + src/include/catalog/index.h | 4 +++- 7 files changed, 31 insertions(+), 11 deletions(-) diff --git a/src/backend/bootstrap/bootstrap.c b/src/backend/bootstrap/bootstrap.c index 68a42de0889..1c8226c6d67 100644 --- a/src/backend/bootstrap/bootstrap.c +++ b/src/backend/bootstrap/bootstrap.c @@ -1181,7 +1181,7 @@ build_indices(void) heap = table_open(ILHead->il_heap, NoLock); ind = index_open(ILHead->il_ind, NoLock); - index_build(heap, ind, ILHead->il_info, false, false); + index_build(heap, ind, ILHead->il_info, false, false, false); index_close(ind, NoLock); table_close(heap, NoLock); diff --git a/src/backend/catalog/heap.c b/src/backend/catalog/heap.c index 5748aa9a1a9..ae6b7cda3dd 100644 --- a/src/backend/catalog/heap.c +++ b/src/backend/catalog/heap.c @@ -3570,7 +3570,8 @@ RelationTruncateIndexes(Relation heapRelation) /* Initialize the index and rebuild */ /* Note: we do not need to re-establish pkey setting */ - index_build(heapRelation, currentIndex, indexInfo, true, false); + index_build(heapRelation, currentIndex, indexInfo, true, false, + true); /* We're done with this index */ index_close(currentIndex, NoLock); diff --git a/src/backend/catalog/index.c b/src/backend/catalog/index.c index de7182a85a9..cfd33f73f48 100644 --- a/src/backend/catalog/index.c +++ b/src/backend/catalog/index.c @@ -715,6 +715,9 @@ UpdateIndexRelation(Oid indexoid, * already exists. * INDEX_CREATE_PARTITIONED: * create a partitioned index (table must be partitioned) + * INDEX_CREATE_REPORT_PROGRESS: + * update the backend's progress information during index build. + * constr_flags: flags passed to index_constraint_create * (only if INDEX_CREATE_ADD_CONSTRAINT is set) * allow_system_table_mods: allow table to be a system catalog @@ -760,6 +763,7 @@ index_create(Relation heapRelation, bool invalid = (flags & INDEX_CREATE_INVALID) != 0; bool concurrent = (flags & INDEX_CREATE_CONCURRENT) != 0; bool partitioned = (flags & INDEX_CREATE_PARTITIONED) != 0; + bool progress = (flags & INDEX_CREATE_REPORT_PROGRESS) != 0; char relkind; TransactionId relfrozenxid; MultiXactId relminmxid; @@ -1276,7 +1280,8 @@ index_create(Relation heapRelation, } else { - index_build(heapRelation, indexRelation, indexInfo, false, true); + index_build(heapRelation, indexRelation, indexInfo, false, true, + progress); } /* @@ -1438,6 +1443,12 @@ index_create_copy(Relation heapRelation, bool concurrently, stattargets[i].isnull = isnull; } + /* + * Note: The current callers do not need INDEX_CREATE_REPORT_PROGRESS.

Second, REPACK (CONCURRENTLY) should not set PROGRESS_REPACK_PHASE to PROGRESS_REPACK_PHASE_FINAL_CLEANUP in rebuild_relation() because it calls finish_heap_swap() anyway (via rebuild_relation_finish_concurrent()), which does the same thing. --- src/backend/bootstrap/bootstrap.c | 2 +- src/backend/catalog/heap.c | 3 ++- src/backend/catalog/index.c | 22 ++++++++++++++++++---- src/backend/catalog/toasting.c | 3 ++- src/backend/commands/cluster.c | 7 ++++--- src/backend/commands/indexcmds.c | 1 + src/include/catalog/index.h | 4 +++- 7 files changed, 31 insertions(+), 11 deletions(-) diff --git a/src/backend/bootstrap/bootstrap.c b/src/backend/bootstrap/bootstrap.c index 68a42de0889..1c8226c6d67 100644 --- a/src/backend/bootstrap/bootstrap.c +++ b/src/backend/bootstrap/bootstrap.c @@ -1181,7 +1181,7 @@ build_indices(void) heap = table_open(ILHead->il_heap, NoLock); ind = index_open(ILHead->il_ind, NoLock); - index_build(heap, ind, ILHead->il_info, false, false); + index_build(heap, ind, ILHead->il_info, false, false, false); index_close(ind, NoLock); table_close(heap, NoLock); diff --git a/src/backend/catalog/heap.c b/src/backend/catalog/heap.c index 5748aa9a1a9..ae6b7cda3dd 100644 --- a/src/backend/catalog/heap.c +++ b/src/backend/catalog/heap.c @@ -3570,7 +3570,8 @@ RelationTruncateIndexes(Relation heapRelation) /* Initialize the index and rebuild */ /* Note: we do not need to re-establish pkey setting */ - index_build(heapRelation, currentIndex, indexInfo, true, false); + index_build(heapRelation, currentIndex, indexInfo, true, false, + true); /* We're done with this index */ index_close(currentIndex, NoLock); diff --git a/src/backend/catalog/index.c b/src/backend/catalog/index.c index 544dd0d6e3d..13284f1d708 100644 --- a/src/backend/catalog/index.c +++ b/src/backend/catalog/index.c @@ -715,6 +715,9 @@ UpdateIndexRelation(Oid indexoid, * already exists. * INDEX_CREATE_PARTITIONED: * create a partitioned index (table must be partitioned) + * INDEX_CREATE_REPORT_PROGRESS: + * update the backend's progress information during index build. + * constr_flags: flags passed to index_constraint_create * (only if INDEX_CREATE_ADD_CONSTRAINT is set) * allow_system_table_mods: allow table to be a system catalog @@ -760,6 +763,7 @@ index_create(Relation heapRelation, bool invalid = (flags & INDEX_CREATE_INVALID) != 0; bool concurrent = (flags & INDEX_CREATE_CONCURRENT) != 0; bool partitioned = (flags & INDEX_CREATE_PARTITIONED) != 0; + bool progress = (flags & INDEX_CREATE_REPORT_PROGRESS) != 0; char relkind; TransactionId relfrozenxid; MultiXactId relminmxid; @@ -1276,7 +1280,8 @@ index_create(Relation heapRelation, } else { - index_build(heapRelation, indexRelation, indexInfo, false, true); + index_build(heapRelation, indexRelation, indexInfo, false, true, + progress); } /* @@ -1455,6 +1460,12 @@ index_create_copy(Relation heapRelation, Oid oldIndexId, Oid tablespaceOid, stattargets[i].isnull = isnull; } + /* + * Note: The current callers do not need INDEX_CREATE_REPORT_PROGRESS.

Second, REPACK (CONCURRENTLY) should not set PROGRESS_REPACK_PHASE to PROGRESS_REPACK_PHASE_FINAL_CLEANUP in rebuild_relation() because it calls finish_heap_swap() anyway (via rebuild_relation_finish_concurrent()), which does the same thing. --- src/backend/bootstrap/bootstrap.c | 2 +- src/backend/catalog/heap.c | 3 ++- src/backend/catalog/index.c | 22 ++++++++++++++++++---- src/backend/catalog/toasting.c | 3 ++- src/backend/commands/cluster.c | 7 ++++--- src/backend/commands/indexcmds.c | 1 + src/include/catalog/index.h | 4 +++- 7 files changed, 31 insertions(+), 11 deletions(-) diff --git a/src/backend/bootstrap/bootstrap.c b/src/backend/bootstrap/bootstrap.c index 17118f2fe76..cb06c52c1d4 100644 --- a/src/backend/bootstrap/bootstrap.c +++ b/src/backend/bootstrap/bootstrap.c @@ -1180,7 +1180,7 @@ build_indices(void) heap = table_open(ILHead->il_heap, NoLock); ind = index_open(ILHead->il_ind, NoLock); - index_build(heap, ind, ILHead->il_info, false, false); + index_build(heap, ind, ILHead->il_info, false, false, false); index_close(ind, NoLock); table_close(heap, NoLock); diff --git a/src/backend/catalog/heap.c b/src/backend/catalog/heap.c index 5748aa9a1a9..ae6b7cda3dd 100644 --- a/src/backend/catalog/heap.c +++ b/src/backend/catalog/heap.c @@ -3570,7 +3570,8 @@ RelationTruncateIndexes(Relation heapRelation) /* Initialize the index and rebuild */ /* Note: we do not need to re-establish pkey setting */ - index_build(heapRelation, currentIndex, indexInfo, true, false); + index_build(heapRelation, currentIndex, indexInfo, true, false, + true); /* We're done with this index */ index_close(currentIndex, NoLock); diff --git a/src/backend/catalog/index.c b/src/backend/catalog/index.c index b1e05d56a1e..89aad2f7b77 100644 --- a/src/backend/catalog/index.c +++ b/src/backend/catalog/index.c @@ -714,6 +714,9 @@ UpdateIndexRelation(Oid indexoid, * already exists. * INDEX_CREATE_PARTITIONED: * create a partitioned index (table must be partitioned) + * INDEX_CREATE_REPORT_PROGRESS: + * update the backend's progress information during index build. + * constr_flags: flags passed to index_constraint_create * (only if INDEX_CREATE_ADD_CONSTRAINT is set) * allow_system_table_mods: allow table to be a system catalog @@ -759,6 +762,7 @@ index_create(Relation heapRelation, bool invalid = (flags & INDEX_CREATE_INVALID) != 0; bool concurrent = (flags & INDEX_CREATE_CONCURRENT) != 0; bool partitioned = (flags & INDEX_CREATE_PARTITIONED) != 0; + bool progress = (flags & INDEX_CREATE_REPORT_PROGRESS) != 0; char relkind; TransactionId relfrozenxid; MultiXactId relminmxid; @@ -1275,7 +1279,8 @@ index_create(Relation heapRelation, } else { - index_build(heapRelation, indexRelation, indexInfo, false, true); + index_build(heapRelation, indexRelation, indexInfo, false, true, + progress); } /* @@ -1454,6 +1459,12 @@ index_create_copy(Relation heapRelation, Oid oldIndexId, Oid tablespaceOid, stattargets[i].isnull = isnull; } + /* + * Note: The current callers do not need INDEX_CREATE_REPORT_PROGRESS.

Second, REPACK (CONCURRENTLY) should not set PROGRESS_REPACK_PHASE to PROGRESS_REPACK_PHASE_FINAL_CLEANUP in rebuild_relation() because it calls finish_heap_swap() anyway (via rebuild_relation_finish_concurrent()), which does the same thing. --- src/backend/bootstrap/bootstrap.c | 2 +- src/backend/catalog/heap.c | 3 ++- src/backend/catalog/index.c | 22 ++++++++++++++++++---- src/backend/catalog/toasting.c | 3 ++- src/backend/commands/cluster.c | 7 ++++--- src/backend/commands/indexcmds.c | 1 + src/include/catalog/index.h | 4 +++- 7 files changed, 31 insertions(+), 11 deletions(-) diff --git a/src/backend/bootstrap/bootstrap.c b/src/backend/bootstrap/bootstrap.c index 68a42de0889..1c8226c6d67 100644 --- a/src/backend/bootstrap/bootstrap.c +++ b/src/backend/bootstrap/bootstrap.c @@ -1181,7 +1181,7 @@ build_indices(void) heap = table_open(ILHead->il_heap, NoLock); ind = index_open(ILHead->il_ind, NoLock); - index_build(heap, ind, ILHead->il_info, false, false); + index_build(heap, ind, ILHead->il_info, false, false, false); index_close(ind, NoLock); table_close(heap, NoLock); diff --git a/src/backend/catalog/heap.c b/src/backend/catalog/heap.c index 5748aa9a1a9..ae6b7cda3dd 100644 --- a/src/backend/catalog/heap.c +++ b/src/backend/catalog/heap.c @@ -3570,7 +3570,8 @@ RelationTruncateIndexes(Relation heapRelation) /* Initialize the index and rebuild */ /* Note: we do not need to re-establish pkey setting */ - index_build(heapRelation, currentIndex, indexInfo, true, false); + index_build(heapRelation, currentIndex, indexInfo, true, false, + true); /* We're done with this index */ index_close(currentIndex, NoLock); diff --git a/src/backend/catalog/index.c b/src/backend/catalog/index.c index 98d38dc5229..1d28202de34 100644 --- a/src/backend/catalog/index.c +++ b/src/backend/catalog/index.c @@ -715,6 +715,9 @@ UpdateIndexRelation(Oid indexoid, * already exists. * INDEX_CREATE_PARTITIONED: * create a partitioned index (table must be partitioned) + * INDEX_CREATE_REPORT_PROGRESS: + * update the backend's progress information during index build. + * constr_flags: flags passed to index_constraint_create * (only if INDEX_CREATE_ADD_CONSTRAINT is set) * allow_system_table_mods: allow table to be a system catalog @@ -760,6 +763,7 @@ index_create(Relation heapRelation, bool invalid = (flags & INDEX_CREATE_INVALID) != 0; bool concurrent = (flags & INDEX_CREATE_CONCURRENT) != 0; bool partitioned = (flags & INDEX_CREATE_PARTITIONED) != 0; + bool progress = (flags & INDEX_CREATE_REPORT_PROGRESS) != 0; char relkind; TransactionId relfrozenxid; MultiXactId relminmxid; @@ -1276,7 +1280,8 @@ index_create(Relation heapRelation, } else { - index_build(heapRelation, indexRelation, indexInfo, false, true); + index_build(heapRelation, indexRelation, indexInfo, false, true, + progress); } /* @@ -1455,6 +1460,12 @@ index_create_copy(Relation heapRelation, Oid oldIndexId, Oid tablespaceOid, stattargets[i].isnull = isnull; } + /* + * Note: The current callers do not need INDEX_CREATE_REPORT_PROGRESS.

Second, REPACK (CONCURRENTLY) should not set PROGRESS_REPACK_PHASE to PROGRESS_REPACK_PHASE_FINAL_CLEANUP in rebuild_relation() because it calls finish_heap_swap() anyway (via rebuild_relation_finish_concurrent()), which does the same thing. --- src/backend/bootstrap/bootstrap.c | 2 +- src/backend/catalog/heap.c | 3 ++- src/backend/catalog/index.c | 22 ++++++++++++++++++---- src/backend/catalog/toasting.c | 3 ++- src/backend/commands/cluster.c | 7 ++++--- src/backend/commands/indexcmds.c | 1 + src/include/catalog/index.h | 4 +++- 7 files changed, 31 insertions(+), 11 deletions(-) diff --git a/src/backend/bootstrap/bootstrap.c b/src/backend/bootstrap/bootstrap.c index 68a42de0889..1c8226c6d67 100644 --- a/src/backend/bootstrap/bootstrap.c +++ b/src/backend/bootstrap/bootstrap.c @@ -1181,7 +1181,7 @@ build_indices(void) heap = table_open(ILHead->il_heap, NoLock); ind = index_open(ILHead->il_ind, NoLock); - index_build(heap, ind, ILHead->il_info, false, false); + index_build(heap, ind, ILHead->il_info, false, false, false); index_close(ind, NoLock); table_close(heap, NoLock); diff --git a/src/backend/catalog/heap.c b/src/backend/catalog/heap.c index 5748aa9a1a9..ae6b7cda3dd 100644 --- a/src/backend/catalog/heap.c +++ b/src/backend/catalog/heap.c @@ -3570,7 +3570,8 @@ RelationTruncateIndexes(Relation heapRelation) /* Initialize the index and rebuild */ /* Note: we do not need to re-establish pkey setting */ - index_build(heapRelation, currentIndex, indexInfo, true, false); + index_build(heapRelation, currentIndex, indexInfo, true, false, + true); /* We're done with this index */ index_close(currentIndex, NoLock); diff --git a/src/backend/catalog/index.c b/src/backend/catalog/index.c index 544dd0d6e3d..13284f1d708 100644 --- a/src/backend/catalog/index.c +++ b/src/backend/catalog/index.c @@ -715,6 +715,9 @@ UpdateIndexRelation(Oid indexoid, * already exists. * INDEX_CREATE_PARTITIONED: * create a partitioned index (table must be partitioned) + * INDEX_CREATE_REPORT_PROGRESS: + * update the backend's progress information during index build. + * constr_flags: flags passed to index_constraint_create * (only if INDEX_CREATE_ADD_CONSTRAINT is set) * allow_system_table_mods: allow table to be a system catalog @@ -760,6 +763,7 @@ index_create(Relation heapRelation, bool invalid = (flags & INDEX_CREATE_INVALID) != 0; bool concurrent = (flags & INDEX_CREATE_CONCURRENT) != 0; bool partitioned = (flags & INDEX_CREATE_PARTITIONED) != 0; + bool progress = (flags & INDEX_CREATE_REPORT_PROGRESS) != 0; char relkind; TransactionId relfrozenxid; MultiXactId relminmxid; @@ -1276,7 +1280,8 @@ index_create(Relation heapRelation, } else { - index_build(heapRelation, indexRelation, indexInfo, false, true); + index_build(heapRelation, indexRelation, indexInfo, false, true, + progress); } /* @@ -1455,6 +1460,12 @@ index_create_copy(Relation heapRelation, Oid oldIndexId, Oid tablespaceOid, stattargets[i].isnull = isnull; } + /* + * Note: The current callers do not need INDEX_CREATE_REPORT_PROGRESS.

Second, REPACK (CONCURRENTLY) should not set PROGRESS_REPACK_PHASE to PROGRESS_REPACK_PHASE_FINAL_CLEANUP in rebuild_relation() because it calls finish_heap_swap() anyway (via rebuild_relation_finish_concurrent()), which does the same thing. --- src/backend/bootstrap/bootstrap.c | 2 +- src/backend/catalog/heap.c | 3 ++- src/backend/catalog/index.c | 22 ++++++++++++++++++---- src/backend/catalog/toasting.c | 3 ++- src/backend/commands/cluster.c | 7 ++++--- src/backend/commands/indexcmds.c | 1 + src/include/catalog/index.h | 4 +++- 7 files changed, 31 insertions(+), 11 deletions(-) diff --git a/src/backend/bootstrap/bootstrap.c b/src/backend/bootstrap/bootstrap.c index 68a42de0889..1c8226c6d67 100644 --- a/src/backend/bootstrap/bootstrap.c +++ b/src/backend/bootstrap/bootstrap.c @@ -1181,7 +1181,7 @@ build_indices(void) heap = table_open(ILHead->il_heap, NoLock); ind = index_open(ILHead->il_ind, NoLock); - index_build(heap, ind, ILHead->il_info, false, false); + index_build(heap, ind, ILHead->il_info, false, false, false); index_close(ind, NoLock); table_close(heap, NoLock); diff --git a/src/backend/catalog/heap.c b/src/backend/catalog/heap.c index 5748aa9a1a9..ae6b7cda3dd 100644 --- a/src/backend/catalog/heap.c +++ b/src/backend/catalog/heap.c @@ -3570,7 +3570,8 @@ RelationTruncateIndexes(Relation heapRelation) /* Initialize the index and rebuild */ /* Note: we do not need to re-establish pkey setting */ - index_build(heapRelation, currentIndex, indexInfo, true, false); + index_build(heapRelation, currentIndex, indexInfo, true, false, + true); /* We're done with this index */ index_close(currentIndex, NoLock); diff --git a/src/backend/catalog/index.c b/src/backend/catalog/index.c index 544dd0d6e3d..13284f1d708 100644 --- a/src/backend/catalog/index.c +++ b/src/backend/catalog/index.c @@ -715,6 +715,9 @@ UpdateIndexRelation(Oid indexoid, * already exists. * INDEX_CREATE_PARTITIONED: * create a partitioned index (table must be partitioned) + * INDEX_CREATE_REPORT_PROGRESS: + * update the backend's progress information during index build. + * constr_flags: flags passed to index_constraint_create * (only if INDEX_CREATE_ADD_CONSTRAINT is set) * allow_system_table_mods: allow table to be a system catalog @@ -760,6 +763,7 @@ index_create(Relation heapRelation, bool invalid = (flags & INDEX_CREATE_INVALID) != 0; bool concurrent = (flags & INDEX_CREATE_CONCURRENT) != 0; bool partitioned = (flags & INDEX_CREATE_PARTITIONED) != 0; + bool progress = (flags & INDEX_CREATE_REPORT_PROGRESS) != 0; char relkind; TransactionId relfrozenxid; MultiXactId relminmxid; @@ -1276,7 +1280,8 @@ index_create(Relation heapRelation, } else { - index_build(heapRelation, indexRelation, indexInfo, false, true); + index_build(heapRelation, indexRelation, indexInfo, false, true, + progress); } /* @@ -1455,6 +1460,12 @@ index_create_copy(Relation heapRelation, Oid oldIndexId, Oid tablespaceOid, stattargets[i].isnull = isnull; } + /* + * Note: The current callers do not need INDEX_CREATE_REPORT_PROGRESS.

Second, REPACK (CONCURRENTLY) should not set PROGRESS_REPACK_PHASE to PROGRESS_REPACK_PHASE_FINAL_CLEANUP in rebuild_relation() because it calls finish_heap_swap() anyway (via rebuild_relation_finish_concurrent()), which does the same thing. --- src/backend/bootstrap/bootstrap.c | 2 +- src/backend/catalog/heap.c | 3 ++- src/backend/catalog/index.c | 22 ++++++++++++++++++---- src/backend/catalog/toasting.c | 3 ++- src/backend/commands/cluster.c | 7 ++++--- src/backend/commands/indexcmds.c | 1 + src/include/catalog/index.h | 4 +++- 7 files changed, 31 insertions(+), 11 deletions(-) diff --git a/src/backend/bootstrap/bootstrap.c b/src/backend/bootstrap/bootstrap.c index 17118f2fe76..cb06c52c1d4 100644 --- a/src/backend/bootstrap/bootstrap.c +++ b/src/backend/bootstrap/bootstrap.c @@ -1180,7 +1180,7 @@ build_indices(void) heap = table_open(ILHead->il_heap, NoLock); ind = index_open(ILHead->il_ind, NoLock); - index_build(heap, ind, ILHead->il_info, false, false); + index_build(heap, ind, ILHead->il_info, false, false, false); index_close(ind, NoLock); table_close(heap, NoLock); diff --git a/src/backend/catalog/heap.c b/src/backend/catalog/heap.c index 5748aa9a1a9..ae6b7cda3dd 100644 --- a/src/backend/catalog/heap.c +++ b/src/backend/catalog/heap.c @@ -3570,7 +3570,8 @@ RelationTruncateIndexes(Relation heapRelation) /* Initialize the index and rebuild */ /* Note: we do not need to re-establish pkey setting */ - index_build(heapRelation, currentIndex, indexInfo, true, false); + index_build(heapRelation, currentIndex, indexInfo, true, false, + true); /* We're done with this index */ index_close(currentIndex, NoLock); diff --git a/src/backend/catalog/index.c b/src/backend/catalog/index.c index b1e05d56a1e..89aad2f7b77 100644 --- a/src/backend/catalog/index.c +++ b/src/backend/catalog/index.c @@ -714,6 +714,9 @@ UpdateIndexRelation(Oid indexoid, * already exists. * INDEX_CREATE_PARTITIONED: * create a partitioned index (table must be partitioned) + * INDEX_CREATE_REPORT_PROGRESS: + * update the backend's progress information during index build. + * constr_flags: flags passed to index_constraint_create * (only if INDEX_CREATE_ADD_CONSTRAINT is set) * allow_system_table_mods: allow table to be a system catalog @@ -759,6 +762,7 @@ index_create(Relation heapRelation, bool invalid = (flags & INDEX_CREATE_INVALID) != 0; bool concurrent = (flags & INDEX_CREATE_CONCURRENT) != 0; bool partitioned = (flags & INDEX_CREATE_PARTITIONED) != 0; + bool progress = (flags & INDEX_CREATE_REPORT_PROGRESS) != 0; char relkind; TransactionId relfrozenxid; MultiXactId relminmxid; @@ -1275,7 +1279,8 @@ index_create(Relation heapRelation, } else { - index_build(heapRelation, indexRelation, indexInfo, false, true); + index_build(heapRelation, indexRelation, indexInfo, false, true, + progress); } /* @@ -1454,6 +1459,12 @@ index_create_copy(Relation heapRelation, Oid oldIndexId, Oid tablespaceOid, stattargets[i].isnull = isnull; } + /* + * Note: The current callers do not need INDEX_CREATE_REPORT_PROGRESS.

Second, REPACK (CONCURRENTLY) should not set PROGRESS_REPACK_PHASE to PROGRESS_REPACK_PHASE_FINAL_CLEANUP in rebuild_relation() because it calls finish_heap_swap() anyway (via rebuild_relation_finish_concurrent()), which does the same thing. --- src/backend/bootstrap/bootstrap.c | 2 +- src/backend/catalog/heap.c | 3 ++- src/backend/catalog/index.c | 22 ++++++++++++++++++---- src/backend/catalog/toasting.c | 3 ++- src/backend/commands/cluster.c | 7 ++++--- src/backend/commands/indexcmds.c | 1 + src/include/catalog/index.h | 4 +++- 7 files changed, 31 insertions(+), 11 deletions(-) diff --git a/src/backend/bootstrap/bootstrap.c b/src/backend/bootstrap/bootstrap.c index 68a42de0889..1c8226c6d67 100644 --- a/src/backend/bootstrap/bootstrap.c +++ b/src/backend/bootstrap/bootstrap.c @@ -1181,7 +1181,7 @@ build_indices(void) heap = table_open(ILHead->il_heap, NoLock); ind = index_open(ILHead->il_ind, NoLock); - index_build(heap, ind, ILHead->il_info, false, false); + index_build(heap, ind, ILHead->il_info, false, false, false); index_close(ind, NoLock); table_close(heap, NoLock); diff --git a/src/backend/catalog/heap.c b/src/backend/catalog/heap.c index 5748aa9a1a9..ae6b7cda3dd 100644 --- a/src/backend/catalog/heap.c +++ b/src/backend/catalog/heap.c @@ -3570,7 +3570,8 @@ RelationTruncateIndexes(Relation heapRelation) /* Initialize the index and rebuild */ /* Note: we do not need to re-establish pkey setting */ - index_build(heapRelation, currentIndex, indexInfo, true, false); + index_build(heapRelation, currentIndex, indexInfo, true, false, + true); /* We're done with this index */ index_close(currentIndex, NoLock); diff --git a/src/backend/catalog/index.c b/src/backend/catalog/index.c index de7182a85a9..cfd33f73f48 100644 --- a/src/backend/catalog/index.c +++ b/src/backend/catalog/index.c @@ -715,6 +715,9 @@ UpdateIndexRelation(Oid indexoid, * already exists. * INDEX_CREATE_PARTITIONED: * create a partitioned index (table must be partitioned) + * INDEX_CREATE_REPORT_PROGRESS: + * update the backend's progress information during index build. + * constr_flags: flags passed to index_constraint_create * (only if INDEX_CREATE_ADD_CONSTRAINT is set) * allow_system_table_mods: allow table to be a system catalog @@ -760,6 +763,7 @@ index_create(Relation heapRelation, bool invalid = (flags & INDEX_CREATE_INVALID) != 0; bool concurrent = (flags & INDEX_CREATE_CONCURRENT) != 0; bool partitioned = (flags & INDEX_CREATE_PARTITIONED) != 0; + bool progress = (flags & INDEX_CREATE_REPORT_PROGRESS) != 0; char relkind; TransactionId relfrozenxid; MultiXactId relminmxid; @@ -1276,7 +1280,8 @@ index_create(Relation heapRelation, } else { - index_build(heapRelation, indexRelation, indexInfo, false, true); + index_build(heapRelation, indexRelation, indexInfo, false, true, + progress); } /* @@ -1438,6 +1443,12 @@ index_create_copy(Relation heapRelation, bool concurrently, stattargets[i].isnull = isnull; } + /* + * Note: The current callers do not need INDEX_CREATE_REPORT_PROGRESS.

Second, REPACK (CONCURRENTLY) should not set PROGRESS_REPACK_PHASE to PROGRESS_REPACK_PHASE_FINAL_CLEANUP in rebuild_relation() because it calls finish_heap_swap() anyway (via rebuild_relation_finish_concurrent()), which does the same thing. --- src/backend/bootstrap/bootstrap.c | 2 +- src/backend/catalog/heap.c | 3 ++- src/backend/catalog/index.c | 22 ++++++++++++++++++---- src/backend/catalog/toasting.c | 3 ++- src/backend/commands/cluster.c | 7 ++++--- src/backend/commands/indexcmds.c | 1 + src/include/catalog/index.h | 4 +++- 7 files changed, 31 insertions(+), 11 deletions(-) diff --git a/src/backend/bootstrap/bootstrap.c b/src/backend/bootstrap/bootstrap.c index 68a42de0889..1c8226c6d67 100644 --- a/src/backend/bootstrap/bootstrap.c +++ b/src/backend/bootstrap/bootstrap.c @@ -1181,7 +1181,7 @@ build_indices(void) heap = table_open(ILHead->il_heap, NoLock); ind = index_open(ILHead->il_ind, NoLock); - index_build(heap, ind, ILHead->il_info, false, false); + index_build(heap, ind, ILHead->il_info, false, false, false); index_close(ind, NoLock); table_close(heap, NoLock); diff --git a/src/backend/catalog/heap.c b/src/backend/catalog/heap.c index 5748aa9a1a9..ae6b7cda3dd 100644 --- a/src/backend/catalog/heap.c +++ b/src/backend/catalog/heap.c @@ -3570,7 +3570,8 @@ RelationTruncateIndexes(Relation heapRelation) /* Initialize the index and rebuild */ /* Note: we do not need to re-establish pkey setting */ - index_build(heapRelation, currentIndex, indexInfo, true, false); + index_build(heapRelation, currentIndex, indexInfo, true, false, + true); /* We're done with this index */ index_close(currentIndex, NoLock); diff --git a/src/backend/catalog/index.c b/src/backend/catalog/index.c index 544dd0d6e3d..13284f1d708 100644 --- a/src/backend/catalog/index.c +++ b/src/backend/catalog/index.c @@ -715,6 +715,9 @@ UpdateIndexRelation(Oid indexoid, * already exists. * INDEX_CREATE_PARTITIONED: * create a partitioned index (table must be partitioned) + * INDEX_CREATE_REPORT_PROGRESS: + * update the backend's progress information during index build. + * constr_flags: flags passed to index_constraint_create * (only if INDEX_CREATE_ADD_CONSTRAINT is set) * allow_system_table_mods: allow table to be a system catalog @@ -760,6 +763,7 @@ index_create(Relation heapRelation, bool invalid = (flags & INDEX_CREATE_INVALID) != 0; bool concurrent = (flags & INDEX_CREATE_CONCURRENT) != 0; bool partitioned = (flags & INDEX_CREATE_PARTITIONED) != 0; + bool progress = (flags & INDEX_CREATE_REPORT_PROGRESS) != 0; char relkind; TransactionId relfrozenxid; MultiXactId relminmxid; @@ -1276,7 +1280,8 @@ index_create(Relation heapRelation, } else { - index_build(heapRelation, indexRelation, indexInfo, false, true); + index_build(heapRelation, indexRelation, indexInfo, false, true, + progress); } /* @@ -1455,6 +1460,12 @@ index_create_copy(Relation heapRelation, Oid oldIndexId, Oid tablespaceOid, stattargets[i].isnull = isnull; } + /* + * Note: The current callers do not need INDEX_CREATE_REPORT_PROGRESS.

Second, REPACK (CONCURRENTLY) should not set PROGRESS_REPACK_PHASE to PROGRESS_REPACK_PHASE_FINAL_CLEANUP in rebuild_relation() because it calls finish_heap_swap() anyway (via rebuild_relation_finish_concurrent()), which does the same thing. --- src/backend/bootstrap/bootstrap.c | 2 +- src/backend/catalog/heap.c | 3 ++- src/backend/catalog/index.c | 22 ++++++++++++++++++---- src/backend/catalog/toasting.c | 3 ++- src/backend/commands/cluster.c | 7 ++++--- src/backend/commands/indexcmds.c | 1 + src/include/catalog/index.h | 4 +++- 7 files changed, 31 insertions(+), 11 deletions(-) diff --git a/src/backend/bootstrap/bootstrap.c b/src/backend/bootstrap/bootstrap.c index 17118f2fe76..cb06c52c1d4 100644 --- a/src/backend/bootstrap/bootstrap.c +++ b/src/backend/bootstrap/bootstrap.c @@ -1180,7 +1180,7 @@ build_indices(void) heap = table_open(ILHead->il_heap, NoLock); ind = index_open(ILHead->il_ind, NoLock); - index_build(heap, ind, ILHead->il_info, false, false); + index_build(heap, ind, ILHead->il_info, false, false, false); index_close(ind, NoLock); table_close(heap, NoLock); diff --git a/src/backend/catalog/heap.c b/src/backend/catalog/heap.c index 5748aa9a1a9..ae6b7cda3dd 100644 --- a/src/backend/catalog/heap.c +++ b/src/backend/catalog/heap.c @@ -3570,7 +3570,8 @@ RelationTruncateIndexes(Relation heapRelation) /* Initialize the index and rebuild */ /* Note: we do not need to re-establish pkey setting */ - index_build(heapRelation, currentIndex, indexInfo, true, false); + index_build(heapRelation, currentIndex, indexInfo, true, false, + true); /* We're done with this index */ index_close(currentIndex, NoLock); diff --git a/src/backend/catalog/index.c b/src/backend/catalog/index.c index b1e05d56a1e..89aad2f7b77 100644 --- a/src/backend/catalog/index.c +++ b/src/backend/catalog/index.c @@ -714,6 +714,9 @@ UpdateIndexRelation(Oid indexoid, * already exists. * INDEX_CREATE_PARTITIONED: * create a partitioned index (table must be partitioned) + * INDEX_CREATE_REPORT_PROGRESS: + * update the backend's progress information during index build. + * constr_flags: flags passed to index_constraint_create * (only if INDEX_CREATE_ADD_CONSTRAINT is set) * allow_system_table_mods: allow table to be a system catalog @@ -759,6 +762,7 @@ index_create(Relation heapRelation, bool invalid = (flags & INDEX_CREATE_INVALID) != 0; bool concurrent = (flags & INDEX_CREATE_CONCURRENT) != 0; bool partitioned = (flags & INDEX_CREATE_PARTITIONED) != 0; + bool progress = (flags & INDEX_CREATE_REPORT_PROGRESS) != 0; char relkind; TransactionId relfrozenxid; MultiXactId relminmxid; @@ -1275,7 +1279,8 @@ index_create(Relation heapRelation, } else { - index_build(heapRelation, indexRelation, indexInfo, false, true); + index_build(heapRelation, indexRelation, indexInfo, false, true, + progress); } /* @@ -1454,6 +1459,12 @@ index_create_copy(Relation heapRelation, Oid oldIndexId, Oid tablespaceOid, stattargets[i].isnull = isnull; } + /* + * Note: The current callers do not need INDEX_CREATE_REPORT_PROGRESS.

Second, REPACK (CONCURRENTLY) should not set PROGRESS_REPACK_PHASE to PROGRESS_REPACK_PHASE_FINAL_CLEANUP in rebuild_relation() because it calls finish_heap_swap() anyway (via rebuild_relation_finish_concurrent()), which does the same thing. --- src/backend/bootstrap/bootstrap.c | 2 +- src/backend/catalog/heap.c | 3 ++- src/backend/catalog/index.c | 22 ++++++++++++++++++---- src/backend/catalog/toasting.c | 3 ++- src/backend/commands/cluster.c | 7 ++++--- src/backend/commands/indexcmds.c | 1 + src/include/catalog/index.h | 4 +++- 7 files changed, 31 insertions(+), 11 deletions(-) diff --git a/src/backend/bootstrap/bootstrap.c b/src/backend/bootstrap/bootstrap.c index 68a42de0889..1c8226c6d67 100644 --- a/src/backend/bootstrap/bootstrap.c +++ b/src/backend/bootstrap/bootstrap.c @@ -1181,7 +1181,7 @@ build_indices(void) heap = table_open(ILHead->il_heap, NoLock); ind = index_open(ILHead->il_ind, NoLock); - index_build(heap, ind, ILHead->il_info, false, false); + index_build(heap, ind, ILHead->il_info, false, false, false); index_close(ind, NoLock); table_close(heap, NoLock); diff --git a/src/backend/catalog/heap.c b/src/backend/catalog/heap.c index 5748aa9a1a9..ae6b7cda3dd 100644 --- a/src/backend/catalog/heap.c +++ b/src/backend/catalog/heap.c @@ -3570,7 +3570,8 @@ RelationTruncateIndexes(Relation heapRelation) /* Initialize the index and rebuild */ /* Note: we do not need to re-establish pkey setting */ - index_build(heapRelation, currentIndex, indexInfo, true, false); + index_build(heapRelation, currentIndex, indexInfo, true, false, + true); /* We're done with this index */ index_close(currentIndex, NoLock); diff --git a/src/backend/catalog/index.c b/src/backend/catalog/index.c index de7182a85a9..cfd33f73f48 100644 --- a/src/backend/catalog/index.c +++ b/src/backend/catalog/index.c @@ -715,6 +715,9 @@ UpdateIndexRelation(Oid indexoid, * already exists. * INDEX_CREATE_PARTITIONED: * create a partitioned index (table must be partitioned) + * INDEX_CREATE_REPORT_PROGRESS: + * update the backend's progress information during index build. + * constr_flags: flags passed to index_constraint_create * (only if INDEX_CREATE_ADD_CONSTRAINT is set) * allow_system_table_mods: allow table to be a system catalog @@ -760,6 +763,7 @@ index_create(Relation heapRelation, bool invalid = (flags & INDEX_CREATE_INVALID) != 0; bool concurrent = (flags & INDEX_CREATE_CONCURRENT) != 0; bool partitioned = (flags & INDEX_CREATE_PARTITIONED) != 0; + bool progress = (flags & INDEX_CREATE_REPORT_PROGRESS) != 0; char relkind; TransactionId relfrozenxid; MultiXactId relminmxid; @@ -1276,7 +1280,8 @@ index_create(Relation heapRelation, } else { - index_build(heapRelation, indexRelation, indexInfo, false, true); + index_build(heapRelation, indexRelation, indexInfo, false, true, + progress); } /* @@ -1438,6 +1443,12 @@ index_create_copy(Relation heapRelation, bool concurrently, stattargets[i].isnull = isnull; } + /* + * Note: The current callers do not need INDEX_CREATE_REPORT_PROGRESS.

Second, REPACK (CONCURRENTLY) should not set PROGRESS_REPACK_PHASE to PROGRESS_REPACK_PHASE_FINAL_CLEANUP in rebuild_relation() because it calls finish_heap_swap() anyway (via rebuild_relation_finish_concurrent()), which does the same thing. --- src/backend/bootstrap/bootstrap.c | 2 +- src/backend/catalog/heap.c | 3 ++- src/backend/catalog/index.c | 22 ++++++++++++++++++---- src/backend/catalog/toasting.c | 3 ++- src/backend/commands/cluster.c | 7 ++++--- src/backend/commands/indexcmds.c | 1 + src/include/catalog/index.h | 4 +++- 7 files changed, 31 insertions(+), 11 deletions(-) diff --git a/src/backend/bootstrap/bootstrap.c b/src/backend/bootstrap/bootstrap.c index 17118f2fe76..cb06c52c1d4 100644 --- a/src/backend/bootstrap/bootstrap.c +++ b/src/backend/bootstrap/bootstrap.c @@ -1180,7 +1180,7 @@ build_indices(void) heap = table_open(ILHead->il_heap, NoLock); ind = index_open(ILHead->il_ind, NoLock); - index_build(heap, ind, ILHead->il_info, false, false); + index_build(heap, ind, ILHead->il_info, false, false, false); index_close(ind, NoLock); table_close(heap, NoLock); diff --git a/src/backend/catalog/heap.c b/src/backend/catalog/heap.c index 5748aa9a1a9..ae6b7cda3dd 100644 --- a/src/backend/catalog/heap.c +++ b/src/backend/catalog/heap.c @@ -3570,7 +3570,8 @@ RelationTruncateIndexes(Relation heapRelation) /* Initialize the index and rebuild */ /* Note: we do not need to re-establish pkey setting */ - index_build(heapRelation, currentIndex, indexInfo, true, false); + index_build(heapRelation, currentIndex, indexInfo, true, false, + true); /* We're done with this index */ index_close(currentIndex, NoLock); diff --git a/src/backend/catalog/index.c b/src/backend/catalog/index.c index b1e05d56a1e..89aad2f7b77 100644 --- a/src/backend/catalog/index.c +++ b/src/backend/catalog/index.c @@ -714,6 +714,9 @@ UpdateIndexRelation(Oid indexoid, * already exists. * INDEX_CREATE_PARTITIONED: * create a partitioned index (table must be partitioned) + * INDEX_CREATE_REPORT_PROGRESS: + * update the backend's progress information during index build. + * constr_flags: flags passed to index_constraint_create * (only if INDEX_CREATE_ADD_CONSTRAINT is set) * allow_system_table_mods: allow table to be a system catalog @@ -759,6 +762,7 @@ index_create(Relation heapRelation, bool invalid = (flags & INDEX_CREATE_INVALID) != 0; bool concurrent = (flags & INDEX_CREATE_CONCURRENT) != 0; bool partitioned = (flags & INDEX_CREATE_PARTITIONED) != 0; + bool progress = (flags & INDEX_CREATE_REPORT_PROGRESS) != 0; char relkind; TransactionId relfrozenxid; MultiXactId relminmxid; @@ -1275,7 +1279,8 @@ index_create(Relation heapRelation, } else { - index_build(heapRelation, indexRelation, indexInfo, false, true); + index_build(heapRelation, indexRelation, indexInfo, false, true, + progress); } /* @@ -1454,6 +1459,12 @@ index_create_copy(Relation heapRelation, Oid oldIndexId, Oid tablespaceOid, stattargets[i].isnull = isnull; } + /* + * Note: The current callers do not need INDEX_CREATE_REPORT_PROGRESS.

Second, REPACK (CONCURRENTLY) should not set PROGRESS_REPACK_PHASE to PROGRESS_REPACK_PHASE_FINAL_CLEANUP in rebuild_relation() because it calls finish_heap_swap() anyway (via rebuild_relation_finish_concurrent()), which does the same thing. --- src/backend/bootstrap/bootstrap.c | 2 +- src/backend/catalog/heap.c | 3 ++- src/backend/catalog/index.c | 22 ++++++++++++++++++---- src/backend/catalog/toasting.c | 3 ++- src/backend/commands/cluster.c | 7 ++++--- src/backend/commands/indexcmds.c | 1 + src/include/catalog/index.h | 4 +++- 7 files changed, 31 insertions(+), 11 deletions(-) diff --git a/src/backend/bootstrap/bootstrap.c b/src/backend/bootstrap/bootstrap.c index 68a42de0889..1c8226c6d67 100644 --- a/src/backend/bootstrap/bootstrap.c +++ b/src/backend/bootstrap/bootstrap.c @@ -1181,7 +1181,7 @@ build_indices(void) heap = table_open(ILHead->il_heap, NoLock); ind = index_open(ILHead->il_ind, NoLock); - index_build(heap, ind, ILHead->il_info, false, false); + index_build(heap, ind, ILHead->il_info, false, false, false); index_close(ind, NoLock); table_close(heap, NoLock); diff --git a/src/backend/catalog/heap.c b/src/backend/catalog/heap.c index 5748aa9a1a9..ae6b7cda3dd 100644 --- a/src/backend/catalog/heap.c +++ b/src/backend/catalog/heap.c @@ -3570,7 +3570,8 @@ RelationTruncateIndexes(Relation heapRelation) /* Initialize the index and rebuild */ /* Note: we do not need to re-establish pkey setting */ - index_build(heapRelation, currentIndex, indexInfo, true, false); + index_build(heapRelation, currentIndex, indexInfo, true, false, + true); /* We're done with this index */ index_close(currentIndex, NoLock); diff --git a/src/backend/catalog/index.c b/src/backend/catalog/index.c index 98d38dc5229..1d28202de34 100644 --- a/src/backend/catalog/index.c +++ b/src/backend/catalog/index.c @@ -715,6 +715,9 @@ UpdateIndexRelation(Oid indexoid, * already exists. * INDEX_CREATE_PARTITIONED: * create a partitioned index (table must be partitioned) + * INDEX_CREATE_REPORT_PROGRESS: + * update the backend's progress information during index build. + * constr_flags: flags passed to index_constraint_create * (only if INDEX_CREATE_ADD_CONSTRAINT is set) * allow_system_table_mods: allow table to be a system catalog @@ -760,6 +763,7 @@ index_create(Relation heapRelation, bool invalid = (flags & INDEX_CREATE_INVALID) != 0; bool concurrent = (flags & INDEX_CREATE_CONCURRENT) != 0; bool partitioned = (flags & INDEX_CREATE_PARTITIONED) != 0; + bool progress = (flags & INDEX_CREATE_REPORT_PROGRESS) != 0; char relkind; TransactionId relfrozenxid; MultiXactId relminmxid; @@ -1276,7 +1280,8 @@ index_create(Relation heapRelation, } else { - index_build(heapRelation, indexRelation, indexInfo, false, true); + index_build(heapRelation, indexRelation, indexInfo, false, true, + progress); } /* @@ -1455,6 +1460,12 @@ index_create_copy(Relation heapRelation, Oid oldIndexId, Oid tablespaceOid, stattargets[i].isnull = isnull; } + /* + * Note: The current callers do not need INDEX_CREATE_REPORT_PROGRESS.

Second, REPACK (CONCURRENTLY) should not set PROGRESS_REPACK_PHASE to PROGRESS_REPACK_PHASE_FINAL_CLEANUP in rebuild_relation() because it calls finish_heap_swap() anyway (via rebuild_relation_finish_concurrent()), which does the same thing. --- src/backend/bootstrap/bootstrap.c | 2 +- src/backend/catalog/heap.c | 3 ++- src/backend/catalog/index.c | 22 ++++++++++++++++++---- src/backend/catalog/toasting.c | 3 ++- src/backend/commands/cluster.c | 7 ++++--- src/backend/commands/indexcmds.c | 1 + src/include/catalog/index.h | 4 +++- 7 files changed, 31 insertions(+), 11 deletions(-) diff --git a/src/backend/bootstrap/bootstrap.c b/src/backend/bootstrap/bootstrap.c index 68a42de0889..1c8226c6d67 100644 --- a/src/backend/bootstrap/bootstrap.c +++ b/src/backend/bootstrap/bootstrap.c @@ -1181,7 +1181,7 @@ build_indices(void) heap = table_open(ILHead->il_heap, NoLock); ind = index_open(ILHead->il_ind, NoLock); - index_build(heap, ind, ILHead->il_info, false, false); + index_build(heap, ind, ILHead->il_info, false, false, false); index_close(ind, NoLock); table_close(heap, NoLock); diff --git a/src/backend/catalog/heap.c b/src/backend/catalog/heap.c index 5748aa9a1a9..ae6b7cda3dd 100644 --- a/src/backend/catalog/heap.c +++ b/src/backend/catalog/heap.c @@ -3570,7 +3570,8 @@ RelationTruncateIndexes(Relation heapRelation) /* Initialize the index and rebuild */ /* Note: we do not need to re-establish pkey setting */ - index_build(heapRelation, currentIndex, indexInfo, true, false); + index_build(heapRelation, currentIndex, indexInfo, true, false, + true); /* We're done with this index */ index_close(currentIndex, NoLock); diff --git a/src/backend/catalog/index.c b/src/backend/catalog/index.c index 544dd0d6e3d..13284f1d708 100644 --- a/src/backend/catalog/index.c +++ b/src/backend/catalog/index.c @@ -715,6 +715,9 @@ UpdateIndexRelation(Oid indexoid, * already exists. * INDEX_CREATE_PARTITIONED: * create a partitioned index (table must be partitioned) + * INDEX_CREATE_REPORT_PROGRESS: + * update the backend's progress information during index build. + * constr_flags: flags passed to index_constraint_create * (only if INDEX_CREATE_ADD_CONSTRAINT is set) * allow_system_table_mods: allow table to be a system catalog @@ -760,6 +763,7 @@ index_create(Relation heapRelation, bool invalid = (flags & INDEX_CREATE_INVALID) != 0; bool concurrent = (flags & INDEX_CREATE_CONCURRENT) != 0; bool partitioned = (flags & INDEX_CREATE_PARTITIONED) != 0; + bool progress = (flags & INDEX_CREATE_REPORT_PROGRESS) != 0; char relkind; TransactionId relfrozenxid; MultiXactId relminmxid; @@ -1276,7 +1280,8 @@ index_create(Relation heapRelation, } else { - index_build(heapRelation, indexRelation, indexInfo, false, true); + index_build(heapRelation, indexRelation, indexInfo, false, true, + progress); } /* @@ -1455,6 +1460,12 @@ index_create_copy(Relation heapRelation, Oid oldIndexId, Oid tablespaceOid, stattargets[i].isnull = isnull; } + /* + * Note: The current callers do not need INDEX_CREATE_REPORT_PROGRESS.

Second, REPACK (CONCURRENTLY) should not set PROGRESS_REPACK_PHASE to PROGRESS_REPACK_PHASE_FINAL_CLEANUP in rebuild_relation() because it calls finish_heap_swap() anyway (via rebuild_relation_finish_concurrent()), which does the same thing. --- src/backend/bootstrap/bootstrap.c | 2 +- src/backend/catalog/heap.c | 3 ++- src/backend/catalog/index.c | 22 ++++++++++++++++++---- src/backend/catalog/toasting.c | 3 ++- src/backend/commands/cluster.c | 7 ++++--- src/backend/commands/indexcmds.c | 1 + src/include/catalog/index.h | 4 +++- 7 files changed, 31 insertions(+), 11 deletions(-) diff --git a/src/backend/bootstrap/bootstrap.c b/src/backend/bootstrap/bootstrap.c index 68a42de0889..1c8226c6d67 100644 --- a/src/backend/bootstrap/bootstrap.c +++ b/src/backend/bootstrap/bootstrap.c @@ -1181,7 +1181,7 @@ build_indices(void) heap = table_open(ILHead->il_heap, NoLock); ind = index_open(ILHead->il_ind, NoLock); - index_build(heap, ind, ILHead->il_info, false, false); + index_build(heap, ind, ILHead->il_info, false, false, false); index_close(ind, NoLock); table_close(heap, NoLock); diff --git a/src/backend/catalog/heap.c b/src/backend/catalog/heap.c index 5748aa9a1a9..ae6b7cda3dd 100644 --- a/src/backend/catalog/heap.c +++ b/src/backend/catalog/heap.c @@ -3570,7 +3570,8 @@ RelationTruncateIndexes(Relation heapRelation) /* Initialize the index and rebuild */ /* Note: we do not need to re-establish pkey setting */ - index_build(heapRelation, currentIndex, indexInfo, true, false); + index_build(heapRelation, currentIndex, indexInfo, true, false, + true); /* We're done with this index */ index_close(currentIndex, NoLock); diff --git a/src/backend/catalog/index.c b/src/backend/catalog/index.c index 98d38dc5229..1d28202de34 100644 --- a/src/backend/catalog/index.c +++ b/src/backend/catalog/index.c @@ -715,6 +715,9 @@ UpdateIndexRelation(Oid indexoid, * already exists. * INDEX_CREATE_PARTITIONED: * create a partitioned index (table must be partitioned) + * INDEX_CREATE_REPORT_PROGRESS: + * update the backend's progress information during index build. + * constr_flags: flags passed to index_constraint_create * (only if INDEX_CREATE_ADD_CONSTRAINT is set) * allow_system_table_mods: allow table to be a system catalog @@ -760,6 +763,7 @@ index_create(Relation heapRelation, bool invalid = (flags & INDEX_CREATE_INVALID) != 0; bool concurrent = (flags & INDEX_CREATE_CONCURRENT) != 0; bool partitioned = (flags & INDEX_CREATE_PARTITIONED) != 0; + bool progress = (flags & INDEX_CREATE_REPORT_PROGRESS) != 0; char relkind; TransactionId relfrozenxid; MultiXactId relminmxid; @@ -1276,7 +1280,8 @@ index_create(Relation heapRelation, } else { - index_build(heapRelation, indexRelation, indexInfo, false, true); + index_build(heapRelation, indexRelation, indexInfo, false, true, + progress); } /* @@ -1455,6 +1460,12 @@ index_create_copy(Relation heapRelation, Oid oldIndexId, Oid tablespaceOid, stattargets[i].isnull = isnull; } + /* + * Note: The current callers do not need INDEX_CREATE_REPORT_PROGRESS.

Second, REPACK (CONCURRENTLY) should not set PROGRESS_REPACK_PHASE to PROGRESS_REPACK_PHASE_FINAL_CLEANUP in rebuild_relation() because it calls finish_heap_swap() anyway (via rebuild_relation_finish_concurrent()), which does the same thing. --- src/backend/bootstrap/bootstrap.c | 2 +- src/backend/catalog/heap.c | 3 ++- src/backend/catalog/index.c | 22 ++++++++++++++++++---- src/backend/catalog/toasting.c | 3 ++- src/backend/commands/cluster.c | 7 ++++--- src/backend/commands/indexcmds.c | 1 + src/include/catalog/index.h | 4 +++- 7 files changed, 31 insertions(+), 11 deletions(-) diff --git a/src/backend/bootstrap/bootstrap.c b/src/backend/bootstrap/bootstrap.c index 68a42de0889..1c8226c6d67 100644 --- a/src/backend/bootstrap/bootstrap.c +++ b/src/backend/bootstrap/bootstrap.c @@ -1181,7 +1181,7 @@ build_indices(void) heap = table_open(ILHead->il_heap, NoLock); ind = index_open(ILHead->il_ind, NoLock); - index_build(heap, ind, ILHead->il_info, false, false); + index_build(heap, ind, ILHead->il_info, false, false, false); index_close(ind, NoLock); table_close(heap, NoLock); diff --git a/src/backend/catalog/heap.c b/src/backend/catalog/heap.c index 5748aa9a1a9..ae6b7cda3dd 100644 --- a/src/backend/catalog/heap.c +++ b/src/backend/catalog/heap.c @@ -3570,7 +3570,8 @@ RelationTruncateIndexes(Relation heapRelation) /* Initialize the index and rebuild */ /* Note: we do not need to re-establish pkey setting */ - index_build(heapRelation, currentIndex, indexInfo, true, false); + index_build(heapRelation, currentIndex, indexInfo, true, false, + true); /* We're done with this index */ index_close(currentIndex, NoLock); diff --git a/src/backend/catalog/index.c b/src/backend/catalog/index.c index 544dd0d6e3d..13284f1d708 100644 --- a/src/backend/catalog/index.c +++ b/src/backend/catalog/index.c @@ -715,6 +715,9 @@ UpdateIndexRelation(Oid indexoid, * already exists. * INDEX_CREATE_PARTITIONED: * create a partitioned index (table must be partitioned) + * INDEX_CREATE_REPORT_PROGRESS: + * update the backend's progress information during index build. + * constr_flags: flags passed to index_constraint_create * (only if INDEX_CREATE_ADD_CONSTRAINT is set) * allow_system_table_mods: allow table to be a system catalog @@ -760,6 +763,7 @@ index_create(Relation heapRelation, bool invalid = (flags & INDEX_CREATE_INVALID) != 0; bool concurrent = (flags & INDEX_CREATE_CONCURRENT) != 0; bool partitioned = (flags & INDEX_CREATE_PARTITIONED) != 0; + bool progress = (flags & INDEX_CREATE_REPORT_PROGRESS) != 0; char relkind; TransactionId relfrozenxid; MultiXactId relminmxid; @@ -1276,7 +1280,8 @@ index_create(Relation heapRelation, } else { - index_build(heapRelation, indexRelation, indexInfo, false, true); + index_build(heapRelation, indexRelation, indexInfo, false, true, + progress); } /* @@ -1455,6 +1460,12 @@ index_create_copy(Relation heapRelation, Oid oldIndexId, Oid tablespaceOid, stattargets[i].isnull = isnull; } + /* + * Note: The current callers do not need INDEX_CREATE_REPORT_PROGRESS.

Second, REPACK (CONCURRENTLY) should not set PROGRESS_REPACK_PHASE to PROGRESS_REPACK_PHASE_FINAL_CLEANUP in rebuild_relation() because it calls finish_heap_swap() anyway (via rebuild_relation_finish_concurrent()), which does the same thing. --- src/backend/bootstrap/bootstrap.c | 2 +- src/backend/catalog/heap.c | 3 ++- src/backend/catalog/index.c | 22 ++++++++++++++++++---- src/backend/catalog/toasting.c | 3 ++- src/backend/commands/cluster.c | 7 ++++--- src/backend/commands/indexcmds.c | 1 + src/include/catalog/index.h | 4 +++- 7 files changed, 31 insertions(+), 11 deletions(-) diff --git a/src/backend/bootstrap/bootstrap.c b/src/backend/bootstrap/bootstrap.c index 68a42de0889..1c8226c6d67 100644 --- a/src/backend/bootstrap/bootstrap.c +++ b/src/backend/bootstrap/bootstrap.c @@ -1181,7 +1181,7 @@ build_indices(void) heap = table_open(ILHead->il_heap, NoLock); ind = index_open(ILHead->il_ind, NoLock); - index_build(heap, ind, ILHead->il_info, false, false); + index_build(heap, ind, ILHead->il_info, false, false, false); index_close(ind, NoLock); table_close(heap, NoLock); diff --git a/src/backend/catalog/heap.c b/src/backend/catalog/heap.c index 5748aa9a1a9..ae6b7cda3dd 100644 --- a/src/backend/catalog/heap.c +++ b/src/backend/catalog/heap.c @@ -3570,7 +3570,8 @@ RelationTruncateIndexes(Relation heapRelation) /* Initialize the index and rebuild */ /* Note: we do not need to re-establish pkey setting */ - index_build(heapRelation, currentIndex, indexInfo, true, false); + index_build(heapRelation, currentIndex, indexInfo, true, false, + true); /* We're done with this index */ index_close(currentIndex, NoLock); diff --git a/src/backend/catalog/index.c b/src/backend/catalog/index.c index de7182a85a9..cfd33f73f48 100644 --- a/src/backend/catalog/index.c +++ b/src/backend/catalog/index.c @@ -715,6 +715,9 @@ UpdateIndexRelation(Oid indexoid, * already exists. * INDEX_CREATE_PARTITIONED: * create a partitioned index (table must be partitioned) + * INDEX_CREATE_REPORT_PROGRESS: + * update the backend's progress information during index build. + * constr_flags: flags passed to index_constraint_create * (only if INDEX_CREATE_ADD_CONSTRAINT is set) * allow_system_table_mods: allow table to be a system catalog @@ -760,6 +763,7 @@ index_create(Relation heapRelation, bool invalid = (flags & INDEX_CREATE_INVALID) != 0; bool concurrent = (flags & INDEX_CREATE_CONCURRENT) != 0; bool partitioned = (flags & INDEX_CREATE_PARTITIONED) != 0; + bool progress = (flags & INDEX_CREATE_REPORT_PROGRESS) != 0; char relkind; TransactionId relfrozenxid; MultiXactId relminmxid; @@ -1276,7 +1280,8 @@ index_create(Relation heapRelation, } else { - index_build(heapRelation, indexRelation, indexInfo, false, true); + index_build(heapRelation, indexRelation, indexInfo, false, true, + progress); } /* @@ -1438,6 +1443,12 @@ index_create_copy(Relation heapRelation, bool concurrently, stattargets[i].isnull = isnull; } + /* + * Note: The current callers do not need INDEX_CREATE_REPORT_PROGRESS.

Second, REPACK (CONCURRENTLY) should not set PROGRESS_REPACK_PHASE to PROGRESS_REPACK_PHASE_FINAL_CLEANUP in rebuild_relation() because it calls finish_heap_swap() anyway (via rebuild_relation_finish_concurrent()), which does the same thing. --- src/backend/bootstrap/bootstrap.c | 2 +- src/backend/catalog/heap.c | 3 ++- src/backend/catalog/index.c | 22 ++++++++++++++++++---- src/backend/catalog/toasting.c | 3 ++- src/backend/commands/cluster.c | 7 ++++--- src/backend/commands/indexcmds.c | 1 + src/include/catalog/index.h | 4 +++- 7 files changed, 31 insertions(+), 11 deletions(-) diff --git a/src/backend/bootstrap/bootstrap.c b/src/backend/bootstrap/bootstrap.c index 68a42de0889..1c8226c6d67 100644 --- a/src/backend/bootstrap/bootstrap.c +++ b/src/backend/bootstrap/bootstrap.c @@ -1181,7 +1181,7 @@ build_indices(void) heap = table_open(ILHead->il_heap, NoLock); ind = index_open(ILHead->il_ind, NoLock); - index_build(heap, ind, ILHead->il_info, false, false); + index_build(heap, ind, ILHead->il_info, false, false, false); index_close(ind, NoLock); table_close(heap, NoLock); diff --git a/src/backend/catalog/heap.c b/src/backend/catalog/heap.c index 5748aa9a1a9..ae6b7cda3dd 100644 --- a/src/backend/catalog/heap.c +++ b/src/backend/catalog/heap.c @@ -3570,7 +3570,8 @@ RelationTruncateIndexes(Relation heapRelation) /* Initialize the index and rebuild */ /* Note: we do not need to re-establish pkey setting */ - index_build(heapRelation, currentIndex, indexInfo, true, false); + index_build(heapRelation, currentIndex, indexInfo, true, false, + true); /* We're done with this index */ index_close(currentIndex, NoLock); diff --git a/src/backend/catalog/index.c b/src/backend/catalog/index.c index 544dd0d6e3d..13284f1d708 100644 --- a/src/backend/catalog/index.c +++ b/src/backend/catalog/index.c @@ -715,6 +715,9 @@ UpdateIndexRelation(Oid indexoid, * already exists. * INDEX_CREATE_PARTITIONED: * create a partitioned index (table must be partitioned) + * INDEX_CREATE_REPORT_PROGRESS: + * update the backend's progress information during index build. + * constr_flags: flags passed to index_constraint_create * (only if INDEX_CREATE_ADD_CONSTRAINT is set) * allow_system_table_mods: allow table to be a system catalog @@ -760,6 +763,7 @@ index_create(Relation heapRelation, bool invalid = (flags & INDEX_CREATE_INVALID) != 0; bool concurrent = (flags & INDEX_CREATE_CONCURRENT) != 0; bool partitioned = (flags & INDEX_CREATE_PARTITIONED) != 0; + bool progress = (flags & INDEX_CREATE_REPORT_PROGRESS) != 0; char relkind; TransactionId relfrozenxid; MultiXactId relminmxid; @@ -1276,7 +1280,8 @@ index_create(Relation heapRelation, } else { - index_build(heapRelation, indexRelation, indexInfo, false, true); + index_build(heapRelation, indexRelation, indexInfo, false, true, + progress); } /* @@ -1455,6 +1460,12 @@ index_create_copy(Relation heapRelation, Oid oldIndexId, Oid tablespaceOid, stattargets[i].isnull = isnull; } + /* + * Note: The current callers do not need INDEX_CREATE_REPORT_PROGRESS.

Second, REPACK (CONCURRENTLY) should not set PROGRESS_REPACK_PHASE to PROGRESS_REPACK_PHASE_FINAL_CLEANUP in rebuild_relation() because it calls finish_heap_swap() anyway (via rebuild_relation_finish_concurrent()), which does the same thing. --- src/backend/bootstrap/bootstrap.c | 2 +- src/backend/catalog/heap.c | 3 ++- src/backend/catalog/index.c | 22 ++++++++++++++++++---- src/backend/catalog/toasting.c | 3 ++- src/backend/commands/cluster.c | 7 ++++--- src/backend/commands/indexcmds.c | 1 + src/include/catalog/index.h | 4 +++- 7 files changed, 31 insertions(+), 11 deletions(-) diff --git a/src/backend/bootstrap/bootstrap.c b/src/backend/bootstrap/bootstrap.c index 68a42de0889..1c8226c6d67 100644 --- a/src/backend/bootstrap/bootstrap.c +++ b/src/backend/bootstrap/bootstrap.c @@ -1181,7 +1181,7 @@ build_indices(void) heap = table_open(ILHead->il_heap, NoLock); ind = index_open(ILHead->il_ind, NoLock); - index_build(heap, ind, ILHead->il_info, false, false); + index_build(heap, ind, ILHead->il_info, false, false, false); index_close(ind, NoLock); table_close(heap, NoLock); diff --git a/src/backend/catalog/heap.c b/src/backend/catalog/heap.c index 5748aa9a1a9..ae6b7cda3dd 100644 --- a/src/backend/catalog/heap.c +++ b/src/backend/catalog/heap.c @@ -3570,7 +3570,8 @@ RelationTruncateIndexes(Relation heapRelation) /* Initialize the index and rebuild */ /* Note: we do not need to re-establish pkey setting */ - index_build(heapRelation, currentIndex, indexInfo, true, false); + index_build(heapRelation, currentIndex, indexInfo, true, false, + true); /* We're done with this index */ index_close(currentIndex, NoLock); diff --git a/src/backend/catalog/index.c b/src/backend/catalog/index.c index de7182a85a9..cfd33f73f48 100644 --- a/src/backend/catalog/index.c +++ b/src/backend/catalog/index.c @@ -715,6 +715,9 @@ UpdateIndexRelation(Oid indexoid, * already exists. * INDEX_CREATE_PARTITIONED: * create a partitioned index (table must be partitioned) + * INDEX_CREATE_REPORT_PROGRESS: + * update the backend's progress information during index build. + * constr_flags: flags passed to index_constraint_create * (only if INDEX_CREATE_ADD_CONSTRAINT is set) * allow_system_table_mods: allow table to be a system catalog @@ -760,6 +763,7 @@ index_create(Relation heapRelation, bool invalid = (flags & INDEX_CREATE_INVALID) != 0; bool concurrent = (flags & INDEX_CREATE_CONCURRENT) != 0; bool partitioned = (flags & INDEX_CREATE_PARTITIONED) != 0; + bool progress = (flags & INDEX_CREATE_REPORT_PROGRESS) != 0; char relkind; TransactionId relfrozenxid; MultiXactId relminmxid; @@ -1276,7 +1280,8 @@ index_create(Relation heapRelation, } else { - index_build(heapRelation, indexRelation, indexInfo, false, true); + index_build(heapRelation, indexRelation, indexInfo, false, true, + progress); } /* @@ -1438,6 +1443,12 @@ index_create_copy(Relation heapRelation, bool concurrently, stattargets[i].isnull = isnull; } + /* + * Note: The current callers do not need INDEX_CREATE_REPORT_PROGRESS.

Second, REPACK (CONCURRENTLY) should not set PROGRESS_REPACK_PHASE to PROGRESS_REPACK_PHASE_FINAL_CLEANUP in rebuild_relation() because it calls finish_heap_swap() anyway (via rebuild_relation_finish_concurrent()), which does the same thing. --- src/backend/bootstrap/bootstrap.c | 2 +- src/backend/catalog/heap.c | 3 ++- src/backend/catalog/index.c | 22 ++++++++++++++++++---- src/backend/catalog/toasting.c | 3 ++- src/backend/commands/cluster.c | 7 ++++--- src/backend/commands/indexcmds.c | 1 + src/include/catalog/index.h | 4 +++- 7 files changed, 31 insertions(+), 11 deletions(-) diff --git a/src/backend/bootstrap/bootstrap.c b/src/backend/bootstrap/bootstrap.c index 17118f2fe76..cb06c52c1d4 100644 --- a/src/backend/bootstrap/bootstrap.c +++ b/src/backend/bootstrap/bootstrap.c @@ -1180,7 +1180,7 @@ build_indices(void) heap = table_open(ILHead->il_heap, NoLock); ind = index_open(ILHead->il_ind, NoLock); - index_build(heap, ind, ILHead->il_info, false, false); + index_build(heap, ind, ILHead->il_info, false, false, false); index_close(ind, NoLock); table_close(heap, NoLock); diff --git a/src/backend/catalog/heap.c b/src/backend/catalog/heap.c index 5748aa9a1a9..ae6b7cda3dd 100644 --- a/src/backend/catalog/heap.c +++ b/src/backend/catalog/heap.c @@ -3570,7 +3570,8 @@ RelationTruncateIndexes(Relation heapRelation) /* Initialize the index and rebuild */ /* Note: we do not need to re-establish pkey setting */ - index_build(heapRelation, currentIndex, indexInfo, true, false); + index_build(heapRelation, currentIndex, indexInfo, true, false, + true); /* We're done with this index */ index_close(currentIndex, NoLock); diff --git a/src/backend/catalog/index.c b/src/backend/catalog/index.c index b1e05d56a1e..89aad2f7b77 100644 --- a/src/backend/catalog/index.c +++ b/src/backend/catalog/index.c @@ -714,6 +714,9 @@ UpdateIndexRelation(Oid indexoid, * already exists. * INDEX_CREATE_PARTITIONED: * create a partitioned index (table must be partitioned) + * INDEX_CREATE_REPORT_PROGRESS: + * update the backend's progress information during index build. + * constr_flags: flags passed to index_constraint_create * (only if INDEX_CREATE_ADD_CONSTRAINT is set) * allow_system_table_mods: allow table to be a system catalog @@ -759,6 +762,7 @@ index_create(Relation heapRelation, bool invalid = (flags & INDEX_CREATE_INVALID) != 0; bool concurrent = (flags & INDEX_CREATE_CONCURRENT) != 0; bool partitioned = (flags & INDEX_CREATE_PARTITIONED) != 0; + bool progress = (flags & INDEX_CREATE_REPORT_PROGRESS) != 0; char relkind; TransactionId relfrozenxid; MultiXactId relminmxid; @@ -1275,7 +1279,8 @@ index_create(Relation heapRelation, } else { - index_build(heapRelation, indexRelation, indexInfo, false, true); + index_build(heapRelation, indexRelation, indexInfo, false, true, + progress); } /* @@ -1454,6 +1459,12 @@ index_create_copy(Relation heapRelation, Oid oldIndexId, Oid tablespaceOid, stattargets[i].isnull = isnull; } + /* + * Note: The current callers do not need INDEX_CREATE_REPORT_PROGRESS.

Second, REPACK (CONCURRENTLY) should not set PROGRESS_REPACK_PHASE to PROGRESS_REPACK_PHASE_FINAL_CLEANUP in rebuild_relation() because it calls finish_heap_swap() anyway (via rebuild_relation_finish_concurrent()), which does the same thing. --- src/backend/bootstrap/bootstrap.c | 2 +- src/backend/catalog/heap.c | 3 ++- src/backend/catalog/index.c | 22 ++++++++++++++++++---- src/backend/catalog/toasting.c | 3 ++- src/backend/commands/cluster.c | 7 ++++--- src/backend/commands/indexcmds.c | 1 + src/include/catalog/index.h | 4 +++- 7 files changed, 31 insertions(+), 11 deletions(-) diff --git a/src/backend/bootstrap/bootstrap.c b/src/backend/bootstrap/bootstrap.c index 68a42de0889..1c8226c6d67 100644 --- a/src/backend/bootstrap/bootstrap.c +++ b/src/backend/bootstrap/bootstrap.c @@ -1181,7 +1181,7 @@ build_indices(void) heap = table_open(ILHead->il_heap, NoLock); ind = index_open(ILHead->il_ind, NoLock); - index_build(heap, ind, ILHead->il_info, false, false); + index_build(heap, ind, ILHead->il_info, false, false, false); index_close(ind, NoLock); table_close(heap, NoLock); diff --git a/src/backend/catalog/heap.c b/src/backend/catalog/heap.c index 5748aa9a1a9..ae6b7cda3dd 100644 --- a/src/backend/catalog/heap.c +++ b/src/backend/catalog/heap.c @@ -3570,7 +3570,8 @@ RelationTruncateIndexes(Relation heapRelation) /* Initialize the index and rebuild */ /* Note: we do not need to re-establish pkey setting */ - index_build(heapRelation, currentIndex, indexInfo, true, false); + index_build(heapRelation, currentIndex, indexInfo, true, false, + true); /* We're done with this index */ index_close(currentIndex, NoLock); diff --git a/src/backend/catalog/index.c b/src/backend/catalog/index.c index de7182a85a9..cfd33f73f48 100644 --- a/src/backend/catalog/index.c +++ b/src/backend/catalog/index.c @@ -715,6 +715,9 @@ UpdateIndexRelation(Oid indexoid, * already exists. * INDEX_CREATE_PARTITIONED: * create a partitioned index (table must be partitioned) + * INDEX_CREATE_REPORT_PROGRESS: + * update the backend's progress information during index build. + * constr_flags: flags passed to index_constraint_create * (only if INDEX_CREATE_ADD_CONSTRAINT is set) * allow_system_table_mods: allow table to be a system catalog @@ -760,6 +763,7 @@ index_create(Relation heapRelation, bool invalid = (flags & INDEX_CREATE_INVALID) != 0; bool concurrent = (flags & INDEX_CREATE_CONCURRENT) != 0; bool partitioned = (flags & INDEX_CREATE_PARTITIONED) != 0; + bool progress = (flags & INDEX_CREATE_REPORT_PROGRESS) != 0; char relkind; TransactionId relfrozenxid; MultiXactId relminmxid; @@ -1276,7 +1280,8 @@ index_create(Relation heapRelation, } else { - index_build(heapRelation, indexRelation, indexInfo, false, true); + index_build(heapRelation, indexRelation, indexInfo, false, true, + progress); } /* @@ -1438,6 +1443,12 @@ index_create_copy(Relation heapRelation, bool concurrently, stattargets[i].isnull = isnull; } + /* + * Note: The current callers do not need INDEX_CREATE_REPORT_PROGRESS.

Second, REPACK (CONCURRENTLY) should not set PROGRESS_REPACK_PHASE to PROGRESS_REPACK_PHASE_FINAL_CLEANUP in rebuild_relation() because it calls finish_heap_swap() anyway (via rebuild_relation_finish_concurrent()), which does the same thing. --- src/backend/bootstrap/bootstrap.c | 2 +- src/backend/catalog/heap.c | 3 ++- src/backend/catalog/index.c | 22 ++++++++++++++++++---- src/backend/catalog/toasting.c | 3 ++- src/backend/commands/cluster.c | 7 ++++--- src/backend/commands/indexcmds.c | 1 + src/include/catalog/index.h | 4 +++- 7 files changed, 31 insertions(+), 11 deletions(-) diff --git a/src/backend/bootstrap/bootstrap.c b/src/backend/bootstrap/bootstrap.c index 68a42de0889..1c8226c6d67 100644 --- a/src/backend/bootstrap/bootstrap.c +++ b/src/backend/bootstrap/bootstrap.c @@ -1181,7 +1181,7 @@ build_indices(void) heap = table_open(ILHead->il_heap, NoLock); ind = index_open(ILHead->il_ind, NoLock); - index_build(heap, ind, ILHead->il_info, false, false); + index_build(heap, ind, ILHead->il_info, false, false, false); index_close(ind, NoLock); table_close(heap, NoLock); diff --git a/src/backend/catalog/heap.c b/src/backend/catalog/heap.c index 5748aa9a1a9..ae6b7cda3dd 100644 --- a/src/backend/catalog/heap.c +++ b/src/backend/catalog/heap.c @@ -3570,7 +3570,8 @@ RelationTruncateIndexes(Relation heapRelation) /* Initialize the index and rebuild */ /* Note: we do not need to re-establish pkey setting */ - index_build(heapRelation, currentIndex, indexInfo, true, false); + index_build(heapRelation, currentIndex, indexInfo, true, false, + true); /* We're done with this index */ index_close(currentIndex, NoLock); diff --git a/src/backend/catalog/index.c b/src/backend/catalog/index.c index 98d38dc5229..1d28202de34 100644 --- a/src/backend/catalog/index.c +++ b/src/backend/catalog/index.c @@ -715,6 +715,9 @@ UpdateIndexRelation(Oid indexoid, * already exists. * INDEX_CREATE_PARTITIONED: * create a partitioned index (table must be partitioned) + * INDEX_CREATE_REPORT_PROGRESS: + * update the backend's progress information during index build. + * constr_flags: flags passed to index_constraint_create * (only if INDEX_CREATE_ADD_CONSTRAINT is set) * allow_system_table_mods: allow table to be a system catalog @@ -760,6 +763,7 @@ index_create(Relation heapRelation, bool invalid = (flags & INDEX_CREATE_INVALID) != 0; bool concurrent = (flags & INDEX_CREATE_CONCURRENT) != 0; bool partitioned = (flags & INDEX_CREATE_PARTITIONED) != 0; + bool progress = (flags & INDEX_CREATE_REPORT_PROGRESS) != 0; char relkind; TransactionId relfrozenxid; MultiXactId relminmxid; @@ -1276,7 +1280,8 @@ index_create(Relation heapRelation, } else { - index_build(heapRelation, indexRelation, indexInfo, false, true); + index_build(heapRelation, indexRelation, indexInfo, false, true, + progress); } /* @@ -1455,6 +1460,12 @@ index_create_copy(Relation heapRelation, Oid oldIndexId, Oid tablespaceOid, stattargets[i].isnull = isnull; } + /* + * Note: The current callers do not need INDEX_CREATE_REPORT_PROGRESS.

Second, REPACK (CONCURRENTLY) should not set PROGRESS_REPACK_PHASE to PROGRESS_REPACK_PHASE_FINAL_CLEANUP in rebuild_relation() because it calls finish_heap_swap() anyway (via rebuild_relation_finish_concurrent()), which does the same thing. --- src/backend/bootstrap/bootstrap.c | 2 +- src/backend/catalog/heap.c | 3 ++- src/backend/catalog/index.c | 22 ++++++++++++++++++---- src/backend/catalog/toasting.c | 3 ++- src/backend/commands/cluster.c | 7 ++++--- src/backend/commands/indexcmds.c | 1 + src/include/catalog/index.h | 4 +++- 7 files changed, 31 insertions(+), 11 deletions(-) diff --git a/src/backend/bootstrap/bootstrap.c b/src/backend/bootstrap/bootstrap.c index 68a42de0889..1c8226c6d67 100644 --- a/src/backend/bootstrap/bootstrap.c +++ b/src/backend/bootstrap/bootstrap.c @@ -1181,7 +1181,7 @@ build_indices(void) heap = table_open(ILHead->il_heap, NoLock); ind = index_open(ILHead->il_ind, NoLock); - index_build(heap, ind, ILHead->il_info, false, false); + index_build(heap, ind, ILHead->il_info, false, false, false); index_close(ind, NoLock); table_close(heap, NoLock); diff --git a/src/backend/catalog/heap.c b/src/backend/catalog/heap.c index 5748aa9a1a9..ae6b7cda3dd 100644 --- a/src/backend/catalog/heap.c +++ b/src/backend/catalog/heap.c @@ -3570,7 +3570,8 @@ RelationTruncateIndexes(Relation heapRelation) /* Initialize the index and rebuild */ /* Note: we do not need to re-establish pkey setting */ - index_build(heapRelation, currentIndex, indexInfo, true, false); + index_build(heapRelation, currentIndex, indexInfo, true, false, + true); /* We're done with this index */ index_close(currentIndex, NoLock); diff --git a/src/backend/catalog/index.c b/src/backend/catalog/index.c index 544dd0d6e3d..13284f1d708 100644 --- a/src/backend/catalog/index.c +++ b/src/backend/catalog/index.c @@ -715,6 +715,9 @@ UpdateIndexRelation(Oid indexoid, * already exists. * INDEX_CREATE_PARTITIONED: * create a partitioned index (table must be partitioned) + * INDEX_CREATE_REPORT_PROGRESS: + * update the backend's progress information during index build. + * constr_flags: flags passed to index_constraint_create * (only if INDEX_CREATE_ADD_CONSTRAINT is set) * allow_system_table_mods: allow table to be a system catalog @@ -760,6 +763,7 @@ index_create(Relation heapRelation, bool invalid = (flags & INDEX_CREATE_INVALID) != 0; bool concurrent = (flags & INDEX_CREATE_CONCURRENT) != 0; bool partitioned = (flags & INDEX_CREATE_PARTITIONED) != 0; + bool progress = (flags & INDEX_CREATE_REPORT_PROGRESS) != 0; char relkind; TransactionId relfrozenxid; MultiXactId relminmxid; @@ -1276,7 +1280,8 @@ index_create(Relation heapRelation, } else { - index_build(heapRelation, indexRelation, indexInfo, false, true); + index_build(heapRelation, indexRelation, indexInfo, false, true, + progress); } /* @@ -1455,6 +1460,12 @@ index_create_copy(Relation heapRelation, Oid oldIndexId, Oid tablespaceOid, stattargets[i].isnull = isnull; } + /* + * Note: The current callers do not need INDEX_CREATE_REPORT_PROGRESS.

Second, REPACK (CONCURRENTLY) should not set PROGRESS_REPACK_PHASE to PROGRESS_REPACK_PHASE_FINAL_CLEANUP in rebuild_relation() because it calls finish_heap_swap() anyway (via rebuild_relation_finish_concurrent()), which does the same thing. --- src/backend/bootstrap/bootstrap.c | 2 +- src/backend/catalog/heap.c | 3 ++- src/backend/catalog/index.c | 22 ++++++++++++++++++---- src/backend/catalog/toasting.c | 3 ++- src/backend/commands/cluster.c | 7 ++++--- src/backend/commands/indexcmds.c | 1 + src/include/catalog/index.h | 4 +++- 7 files changed, 31 insertions(+), 11 deletions(-) diff --git a/src/backend/bootstrap/bootstrap.c b/src/backend/bootstrap/bootstrap.c index 68a42de0889..1c8226c6d67 100644 --- a/src/backend/bootstrap/bootstrap.c +++ b/src/backend/bootstrap/bootstrap.c @@ -1181,7 +1181,7 @@ build_indices(void) heap = table_open(ILHead->il_heap, NoLock); ind = index_open(ILHead->il_ind, NoLock); - index_build(heap, ind, ILHead->il_info, false, false); + index_build(heap, ind, ILHead->il_info, false, false, false); index_close(ind, NoLock); table_close(heap, NoLock); diff --git a/src/backend/catalog/heap.c b/src/backend/catalog/heap.c index 5748aa9a1a9..ae6b7cda3dd 100644 --- a/src/backend/catalog/heap.c +++ b/src/backend/catalog/heap.c @@ -3570,7 +3570,8 @@ RelationTruncateIndexes(Relation heapRelation) /* Initialize the index and rebuild */ /* Note: we do not need to re-establish pkey setting */ - index_build(heapRelation, currentIndex, indexInfo, true, false); + index_build(heapRelation, currentIndex, indexInfo, true, false, + true); /* We're done with this index */ index_close(currentIndex, NoLock); diff --git a/src/backend/catalog/index.c b/src/backend/catalog/index.c index de7182a85a9..cfd33f73f48 100644 --- a/src/backend/catalog/index.c +++ b/src/backend/catalog/index.c @@ -715,6 +715,9 @@ UpdateIndexRelation(Oid indexoid, * already exists. * INDEX_CREATE_PARTITIONED: * create a partitioned index (table must be partitioned) + * INDEX_CREATE_REPORT_PROGRESS: + * update the backend's progress information during index build. + * constr_flags: flags passed to index_constraint_create * (only if INDEX_CREATE_ADD_CONSTRAINT is set) * allow_system_table_mods: allow table to be a system catalog @@ -760,6 +763,7 @@ index_create(Relation heapRelation, bool invalid = (flags & INDEX_CREATE_INVALID) != 0; bool concurrent = (flags & INDEX_CREATE_CONCURRENT) != 0; bool partitioned = (flags & INDEX_CREATE_PARTITIONED) != 0; + bool progress = (flags & INDEX_CREATE_REPORT_PROGRESS) != 0; char relkind; TransactionId relfrozenxid; MultiXactId relminmxid; @@ -1276,7 +1280,8 @@ index_create(Relation heapRelation, } else { - index_build(heapRelation, indexRelation, indexInfo, false, true); + index_build(heapRelation, indexRelation, indexInfo, false, true, + progress); } /* @@ -1438,6 +1443,12 @@ index_create_copy(Relation heapRelation, bool concurrently, stattargets[i].isnull = isnull; } + /* + * Note: The current callers do not need INDEX_CREATE_REPORT_PROGRESS.

Second, REPACK (CONCURRENTLY) should not set PROGRESS_REPACK_PHASE to PROGRESS_REPACK_PHASE_FINAL_CLEANUP in rebuild_relation() because it calls finish_heap_swap() anyway (via rebuild_relation_finish_concurrent()), which does the same thing. --- src/backend/bootstrap/bootstrap.c | 2 +- src/backend/catalog/heap.c | 3 ++- src/backend/catalog/index.c | 22 ++++++++++++++++++---- src/backend/catalog/toasting.c | 3 ++- src/backend/commands/cluster.c | 7 ++++--- src/backend/commands/indexcmds.c | 1 + src/include/catalog/index.h | 4 +++- 7 files changed, 31 insertions(+), 11 deletions(-) diff --git a/src/backend/bootstrap/bootstrap.c b/src/backend/bootstrap/bootstrap.c index 17118f2fe76..cb06c52c1d4 100644 --- a/src/backend/bootstrap/bootstrap.c +++ b/src/backend/bootstrap/bootstrap.c @@ -1180,7 +1180,7 @@ build_indices(void) heap = table_open(ILHead->il_heap, NoLock); ind = index_open(ILHead->il_ind, NoLock); - index_build(heap, ind, ILHead->il_info, false, false); + index_build(heap, ind, ILHead->il_info, false, false, false); index_close(ind, NoLock); table_close(heap, NoLock); diff --git a/src/backend/catalog/heap.c b/src/backend/catalog/heap.c index 5748aa9a1a9..ae6b7cda3dd 100644 --- a/src/backend/catalog/heap.c +++ b/src/backend/catalog/heap.c @@ -3570,7 +3570,8 @@ RelationTruncateIndexes(Relation heapRelation) /* Initialize the index and rebuild */ /* Note: we do not need to re-establish pkey setting */ - index_build(heapRelation, currentIndex, indexInfo, true, false); + index_build(heapRelation, currentIndex, indexInfo, true, false, + true); /* We're done with this index */ index_close(currentIndex, NoLock); diff --git a/src/backend/catalog/index.c b/src/backend/catalog/index.c index b1e05d56a1e..89aad2f7b77 100644 --- a/src/backend/catalog/index.c +++ b/src/backend/catalog/index.c @@ -714,6 +714,9 @@ UpdateIndexRelation(Oid indexoid, * already exists. * INDEX_CREATE_PARTITIONED: * create a partitioned index (table must be partitioned) + * INDEX_CREATE_REPORT_PROGRESS: + * update the backend's progress information during index build. + * constr_flags: flags passed to index_constraint_create * (only if INDEX_CREATE_ADD_CONSTRAINT is set) * allow_system_table_mods: allow table to be a system catalog @@ -759,6 +762,7 @@ index_create(Relation heapRelation, bool invalid = (flags & INDEX_CREATE_INVALID) != 0; bool concurrent = (flags & INDEX_CREATE_CONCURRENT) != 0; bool partitioned = (flags & INDEX_CREATE_PARTITIONED) != 0; + bool progress = (flags & INDEX_CREATE_REPORT_PROGRESS) != 0; char relkind; TransactionId relfrozenxid; MultiXactId relminmxid; @@ -1275,7 +1279,8 @@ index_create(Relation heapRelation, } else { - index_build(heapRelation, indexRelation, indexInfo, false, true); + index_build(heapRelation, indexRelation, indexInfo, false, true, + progress); } /* @@ -1454,6 +1459,12 @@ index_create_copy(Relation heapRelation, Oid oldIndexId, Oid tablespaceOid, stattargets[i].isnull = isnull; } + /* + * Note: The current callers do not need INDEX_CREATE_REPORT_PROGRESS.

Second, REPACK (CONCURRENTLY) should not set PROGRESS_REPACK_PHASE to PROGRESS_REPACK_PHASE_FINAL_CLEANUP in rebuild_relation() because it calls finish_heap_swap() anyway (via rebuild_relation_finish_concurrent()), which does the same thing. --- src/backend/bootstrap/bootstrap.c | 2 +- src/backend/catalog/heap.c | 3 ++- src/backend/catalog/index.c | 22 ++++++++++++++++++---- src/backend/catalog/toasting.c | 3 ++- src/backend/commands/cluster.c | 7 ++++--- src/backend/commands/indexcmds.c | 1 + src/include/catalog/index.h | 4 +++- 7 files changed, 31 insertions(+), 11 deletions(-) diff --git a/src/backend/bootstrap/bootstrap.c b/src/backend/bootstrap/bootstrap.c index 17118f2fe76..cb06c52c1d4 100644 --- a/src/backend/bootstrap/bootstrap.c +++ b/src/backend/bootstrap/bootstrap.c @@ -1180,7 +1180,7 @@ build_indices(void) heap = table_open(ILHead->il_heap, NoLock); ind = index_open(ILHead->il_ind, NoLock); - index_build(heap, ind, ILHead->il_info, false, false); + index_build(heap, ind, ILHead->il_info, false, false, false); index_close(ind, NoLock); table_close(heap, NoLock); diff --git a/src/backend/catalog/heap.c b/src/backend/catalog/heap.c index 5748aa9a1a9..ae6b7cda3dd 100644 --- a/src/backend/catalog/heap.c +++ b/src/backend/catalog/heap.c @@ -3570,7 +3570,8 @@ RelationTruncateIndexes(Relation heapRelation) /* Initialize the index and rebuild */ /* Note: we do not need to re-establish pkey setting */ - index_build(heapRelation, currentIndex, indexInfo, true, false); + index_build(heapRelation, currentIndex, indexInfo, true, false, + true); /* We're done with this index */ index_close(currentIndex, NoLock); diff --git a/src/backend/catalog/index.c b/src/backend/catalog/index.c index b1e05d56a1e..89aad2f7b77 100644 --- a/src/backend/catalog/index.c +++ b/src/backend/catalog/index.c @@ -714,6 +714,9 @@ UpdateIndexRelation(Oid indexoid, * already exists. * INDEX_CREATE_PARTITIONED: * create a partitioned index (table must be partitioned) + * INDEX_CREATE_REPORT_PROGRESS: + * update the backend's progress information during index build. + * constr_flags: flags passed to index_constraint_create * (only if INDEX_CREATE_ADD_CONSTRAINT is set) * allow_system_table_mods: allow table to be a system catalog @@ -759,6 +762,7 @@ index_create(Relation heapRelation, bool invalid = (flags & INDEX_CREATE_INVALID) != 0; bool concurrent = (flags & INDEX_CREATE_CONCURRENT) != 0; bool partitioned = (flags & INDEX_CREATE_PARTITIONED) != 0; + bool progress = (flags & INDEX_CREATE_REPORT_PROGRESS) != 0; char relkind; TransactionId relfrozenxid; MultiXactId relminmxid; @@ -1275,7 +1279,8 @@ index_create(Relation heapRelation, } else { - index_build(heapRelation, indexRelation, indexInfo, false, true); + index_build(heapRelation, indexRelation, indexInfo, false, true, + progress); } /* @@ -1454,6 +1459,12 @@ index_create_copy(Relation heapRelation, Oid oldIndexId, Oid tablespaceOid, stattargets[i].isnull = isnull; } + /* + * Note: The current callers do not need INDEX_CREATE_REPORT_PROGRESS.

Second, REPACK (CONCURRENTLY) should not set PROGRESS_REPACK_PHASE to PROGRESS_REPACK_PHASE_FINAL_CLEANUP in rebuild_relation() because it calls finish_heap_swap() anyway (via rebuild_relation_finish_concurrent()), which does the same thing. --- src/backend/bootstrap/bootstrap.c | 2 +- src/backend/catalog/heap.c | 3 ++- src/backend/catalog/index.c | 22 ++++++++++++++++++---- src/backend/catalog/toasting.c | 3 ++- src/backend/commands/cluster.c | 7 ++++--- src/backend/commands/indexcmds.c | 1 + src/include/catalog/index.h | 4 +++- 7 files changed, 31 insertions(+), 11 deletions(-) diff --git a/src/backend/bootstrap/bootstrap.c b/src/backend/bootstrap/bootstrap.c index 17118f2fe76..cb06c52c1d4 100644 --- a/src/backend/bootstrap/bootstrap.c +++ b/src/backend/bootstrap/bootstrap.c @@ -1180,7 +1180,7 @@ build_indices(void) heap = table_open(ILHead->il_heap, NoLock); ind = index_open(ILHead->il_ind, NoLock); - index_build(heap, ind, ILHead->il_info, false, false); + index_build(heap, ind, ILHead->il_info, false, false, false); index_close(ind, NoLock); table_close(heap, NoLock); diff --git a/src/backend/catalog/heap.c b/src/backend/catalog/heap.c index 5748aa9a1a9..ae6b7cda3dd 100644 --- a/src/backend/catalog/heap.c +++ b/src/backend/catalog/heap.c @@ -3570,7 +3570,8 @@ RelationTruncateIndexes(Relation heapRelation) /* Initialize the index and rebuild */ /* Note: we do not need to re-establish pkey setting */ - index_build(heapRelation, currentIndex, indexInfo, true, false); + index_build(heapRelation, currentIndex, indexInfo, true, false, + true); /* We're done with this index */ index_close(currentIndex, NoLock); diff --git a/src/backend/catalog/index.c b/src/backend/catalog/index.c index b1e05d56a1e..89aad2f7b77 100644 --- a/src/backend/catalog/index.c +++ b/src/backend/catalog/index.c @@ -714,6 +714,9 @@ UpdateIndexRelation(Oid indexoid, * already exists. * INDEX_CREATE_PARTITIONED: * create a partitioned index (table must be partitioned) + * INDEX_CREATE_REPORT_PROGRESS: + * update the backend's progress information during index build. + * constr_flags: flags passed to index_constraint_create * (only if INDEX_CREATE_ADD_CONSTRAINT is set) * allow_system_table_mods: allow table to be a system catalog @@ -759,6 +762,7 @@ index_create(Relation heapRelation, bool invalid = (flags & INDEX_CREATE_INVALID) != 0; bool concurrent = (flags & INDEX_CREATE_CONCURRENT) != 0; bool partitioned = (flags & INDEX_CREATE_PARTITIONED) != 0; + bool progress = (flags & INDEX_CREATE_REPORT_PROGRESS) != 0; char relkind; TransactionId relfrozenxid; MultiXactId relminmxid; @@ -1275,7 +1279,8 @@ index_create(Relation heapRelation, } else { - index_build(heapRelation, indexRelation, indexInfo, false, true); + index_build(heapRelation, indexRelation, indexInfo, false, true, + progress); } /* @@ -1454,6 +1459,12 @@ index_create_copy(Relation heapRelation, Oid oldIndexId, Oid tablespaceOid, stattargets[i].isnull = isnull; } + /* + * Note: The current callers do not need INDEX_CREATE_REPORT_PROGRESS.

Second, REPACK (CONCURRENTLY) should not set PROGRESS_REPACK_PHASE to PROGRESS_REPACK_PHASE_FINAL_CLEANUP in rebuild_relation() because it calls finish_heap_swap() anyway (via rebuild_relation_finish_concurrent()), which does the same thing. --- src/backend/bootstrap/bootstrap.c | 2 +- src/backend/catalog/heap.c | 3 ++- src/backend/catalog/index.c | 22 ++++++++++++++++++---- src/backend/catalog/toasting.c | 3 ++- src/backend/commands/cluster.c | 7 ++++--- src/backend/commands/indexcmds.c | 1 + src/include/catalog/index.h | 4 +++- 7 files changed, 31 insertions(+), 11 deletions(-) diff --git a/src/backend/bootstrap/bootstrap.c b/src/backend/bootstrap/bootstrap.c index 68a42de0889..1c8226c6d67 100644 --- a/src/backend/bootstrap/bootstrap.c +++ b/src/backend/bootstrap/bootstrap.c @@ -1181,7 +1181,7 @@ build_indices(void) heap = table_open(ILHead->il_heap, NoLock); ind = index_open(ILHead->il_ind, NoLock); - index_build(heap, ind, ILHead->il_info, false, false); + index_build(heap, ind, ILHead->il_info, false, false, false); index_close(ind, NoLock); table_close(heap, NoLock); diff --git a/src/backend/catalog/heap.c b/src/backend/catalog/heap.c index 5748aa9a1a9..ae6b7cda3dd 100644 --- a/src/backend/catalog/heap.c +++ b/src/backend/catalog/heap.c @@ -3570,7 +3570,8 @@ RelationTruncateIndexes(Relation heapRelation) /* Initialize the index and rebuild */ /* Note: we do not need to re-establish pkey setting */ - index_build(heapRelation, currentIndex, indexInfo, true, false); + index_build(heapRelation, currentIndex, indexInfo, true, false, + true); /* We're done with this index */ index_close(currentIndex, NoLock); diff --git a/src/backend/catalog/index.c b/src/backend/catalog/index.c index 544dd0d6e3d..13284f1d708 100644 --- a/src/backend/catalog/index.c +++ b/src/backend/catalog/index.c @@ -715,6 +715,9 @@ UpdateIndexRelation(Oid indexoid, * already exists. * INDEX_CREATE_PARTITIONED: * create a partitioned index (table must be partitioned) + * INDEX_CREATE_REPORT_PROGRESS: + * update the backend's progress information during index build. + * constr_flags: flags passed to index_constraint_create * (only if INDEX_CREATE_ADD_CONSTRAINT is set) * allow_system_table_mods: allow table to be a system catalog @@ -760,6 +763,7 @@ index_create(Relation heapRelation, bool invalid = (flags & INDEX_CREATE_INVALID) != 0; bool concurrent = (flags & INDEX_CREATE_CONCURRENT) != 0; bool partitioned = (flags & INDEX_CREATE_PARTITIONED) != 0; + bool progress = (flags & INDEX_CREATE_REPORT_PROGRESS) != 0; char relkind; TransactionId relfrozenxid; MultiXactId relminmxid; @@ -1276,7 +1280,8 @@ index_create(Relation heapRelation, } else { - index_build(heapRelation, indexRelation, indexInfo, false, true); + index_build(heapRelation, indexRelation, indexInfo, false, true, + progress); } /* @@ -1455,6 +1460,12 @@ index_create_copy(Relation heapRelation, Oid oldIndexId, Oid tablespaceOid, stattargets[i].isnull = isnull; } + /* + * Note: The current callers do not need INDEX_CREATE_REPORT_PROGRESS.

Second, REPACK (CONCURRENTLY) should not set PROGRESS_REPACK_PHASE to PROGRESS_REPACK_PHASE_FINAL_CLEANUP in rebuild_relation() because it calls finish_heap_swap() anyway (via rebuild_relation_finish_concurrent()), which does the same thing. --- src/backend/bootstrap/bootstrap.c | 2 +- src/backend/catalog/heap.c | 3 ++- src/backend/catalog/index.c | 22 ++++++++++++++++++---- src/backend/catalog/toasting.c | 3 ++- src/backend/commands/cluster.c | 7 ++++--- src/backend/commands/indexcmds.c | 1 + src/include/catalog/index.h | 4 +++- 7 files changed, 31 insertions(+), 11 deletions(-) diff --git a/src/backend/bootstrap/bootstrap.c b/src/backend/bootstrap/bootstrap.c index 17118f2fe76..cb06c52c1d4 100644 --- a/src/backend/bootstrap/bootstrap.c +++ b/src/backend/bootstrap/bootstrap.c @@ -1180,7 +1180,7 @@ build_indices(void) heap = table_open(ILHead->il_heap, NoLock); ind = index_open(ILHead->il_ind, NoLock); - index_build(heap, ind, ILHead->il_info, false, false); + index_build(heap, ind, ILHead->il_info, false, false, false); index_close(ind, NoLock); table_close(heap, NoLock); diff --git a/src/backend/catalog/heap.c b/src/backend/catalog/heap.c index 5748aa9a1a9..ae6b7cda3dd 100644 --- a/src/backend/catalog/heap.c +++ b/src/backend/catalog/heap.c @@ -3570,7 +3570,8 @@ RelationTruncateIndexes(Relation heapRelation) /* Initialize the index and rebuild */ /* Note: we do not need to re-establish pkey setting */ - index_build(heapRelation, currentIndex, indexInfo, true, false); + index_build(heapRelation, currentIndex, indexInfo, true, false, + true); /* We're done with this index */ index_close(currentIndex, NoLock); diff --git a/src/backend/catalog/index.c b/src/backend/catalog/index.c index b1e05d56a1e..89aad2f7b77 100644 --- a/src/backend/catalog/index.c +++ b/src/backend/catalog/index.c @@ -714,6 +714,9 @@ UpdateIndexRelation(Oid indexoid, * already exists. * INDEX_CREATE_PARTITIONED: * create a partitioned index (table must be partitioned) + * INDEX_CREATE_REPORT_PROGRESS: + * update the backend's progress information during index build. + * constr_flags: flags passed to index_constraint_create * (only if INDEX_CREATE_ADD_CONSTRAINT is set) * allow_system_table_mods: allow table to be a system catalog @@ -759,6 +762,7 @@ index_create(Relation heapRelation, bool invalid = (flags & INDEX_CREATE_INVALID) != 0; bool concurrent = (flags & INDEX_CREATE_CONCURRENT) != 0; bool partitioned = (flags & INDEX_CREATE_PARTITIONED) != 0; + bool progress = (flags & INDEX_CREATE_REPORT_PROGRESS) != 0; char relkind; TransactionId relfrozenxid; MultiXactId relminmxid; @@ -1275,7 +1279,8 @@ index_create(Relation heapRelation, } else { - index_build(heapRelation, indexRelation, indexInfo, false, true); + index_build(heapRelation, indexRelation, indexInfo, false, true, + progress); } /* @@ -1454,6 +1459,12 @@ index_create_copy(Relation heapRelation, Oid oldIndexId, Oid tablespaceOid, stattargets[i].isnull = isnull; } + /* + * Note: The current callers do not need INDEX_CREATE_REPORT_PROGRESS.

Second, REPACK (CONCURRENTLY) should not set PROGRESS_REPACK_PHASE to PROGRESS_REPACK_PHASE_FINAL_CLEANUP in rebuild_relation() because it calls finish_heap_swap() anyway (via rebuild_relation_finish_concurrent()), which does the same thing. --- src/backend/bootstrap/bootstrap.c | 2 +- src/backend/catalog/heap.c | 3 ++- src/backend/catalog/index.c | 22 ++++++++++++++++++---- src/backend/catalog/toasting.c | 3 ++- src/backend/commands/cluster.c | 7 ++++--- src/backend/commands/indexcmds.c | 1 + src/include/catalog/index.h | 4 +++- 7 files changed, 31 insertions(+), 11 deletions(-) diff --git a/src/backend/bootstrap/bootstrap.c b/src/backend/bootstrap/bootstrap.c index 68a42de0889..1c8226c6d67 100644 --- a/src/backend/bootstrap/bootstrap.c +++ b/src/backend/bootstrap/bootstrap.c @@ -1181,7 +1181,7 @@ build_indices(void) heap = table_open(ILHead->il_heap, NoLock); ind = index_open(ILHead->il_ind, NoLock); - index_build(heap, ind, ILHead->il_info, false, false); + index_build(heap, ind, ILHead->il_info, false, false, false); index_close(ind, NoLock); table_close(heap, NoLock); diff --git a/src/backend/catalog/heap.c b/src/backend/catalog/heap.c index 5748aa9a1a9..ae6b7cda3dd 100644 --- a/src/backend/catalog/heap.c +++ b/src/backend/catalog/heap.c @@ -3570,7 +3570,8 @@ RelationTruncateIndexes(Relation heapRelation) /* Initialize the index and rebuild */ /* Note: we do not need to re-establish pkey setting */ - index_build(heapRelation, currentIndex, indexInfo, true, false); + index_build(heapRelation, currentIndex, indexInfo, true, false, + true); /* We're done with this index */ index_close(currentIndex, NoLock); diff --git a/src/backend/catalog/index.c b/src/backend/catalog/index.c index de7182a85a9..cfd33f73f48 100644 --- a/src/backend/catalog/index.c +++ b/src/backend/catalog/index.c @@ -715,6 +715,9 @@ UpdateIndexRelation(Oid indexoid, * already exists. * INDEX_CREATE_PARTITIONED: * create a partitioned index (table must be partitioned) + * INDEX_CREATE_REPORT_PROGRESS: + * update the backend's progress information during index build. + * constr_flags: flags passed to index_constraint_create * (only if INDEX_CREATE_ADD_CONSTRAINT is set) * allow_system_table_mods: allow table to be a system catalog @@ -760,6 +763,7 @@ index_create(Relation heapRelation, bool invalid = (flags & INDEX_CREATE_INVALID) != 0; bool concurrent = (flags & INDEX_CREATE_CONCURRENT) != 0; bool partitioned = (flags & INDEX_CREATE_PARTITIONED) != 0; + bool progress = (flags & INDEX_CREATE_REPORT_PROGRESS) != 0; char relkind; TransactionId relfrozenxid; MultiXactId relminmxid; @@ -1276,7 +1280,8 @@ index_create(Relation heapRelation, } else { - index_build(heapRelation, indexRelation, indexInfo, false, true); + index_build(heapRelation, indexRelation, indexInfo, false, true, + progress); } /* @@ -1438,6 +1443,12 @@ index_create_copy(Relation heapRelation, bool concurrently, stattargets[i].isnull = isnull; } + /* + * Note: The current callers do not need INDEX_CREATE_REPORT_PROGRESS.

Second, REPACK (CONCURRENTLY) should not set PROGRESS_REPACK_PHASE to PROGRESS_REPACK_PHASE_FINAL_CLEANUP in rebuild_relation() because it calls finish_heap_swap() anyway (via rebuild_relation_finish_concurrent()), which does the same thing. --- src/backend/bootstrap/bootstrap.c | 2 +- src/backend/catalog/heap.c | 3 ++- src/backend/catalog/index.c | 22 ++++++++++++++++++---- src/backend/catalog/toasting.c | 3 ++- src/backend/commands/indexcmds.c | 1 + src/include/catalog/index.h | 4 +++- 6 files changed, 27 insertions(+), 8 deletions(-) diff --git a/src/backend/bootstrap/bootstrap.c b/src/backend/bootstrap/bootstrap.c index 38ef683d4c7..60fb7051830 100644 --- a/src/backend/bootstrap/bootstrap.c +++ b/src/backend/bootstrap/bootstrap.c @@ -1183,7 +1183,7 @@ build_indices(void) heap = table_open(ILHead->il_heap, NoLock); ind = index_open(ILHead->il_ind, NoLock); - index_build(heap, ind, ILHead->il_info, false, false); + index_build(heap, ind, ILHead->il_info, false, false, false); index_close(ind, NoLock); table_close(heap, NoLock); diff --git a/src/backend/catalog/heap.c b/src/backend/catalog/heap.c index 5748aa9a1a9..ae6b7cda3dd 100644 --- a/src/backend/catalog/heap.c +++ b/src/backend/catalog/heap.c @@ -3570,7 +3570,8 @@ RelationTruncateIndexes(Relation heapRelation) /* Initialize the index and rebuild */ /* Note: we do not need to re-establish pkey setting */ - index_build(heapRelation, currentIndex, indexInfo, true, false); + index_build(heapRelation, currentIndex, indexInfo, true, false, + true); /* We're done with this index */ index_close(currentIndex, NoLock); diff --git a/src/backend/catalog/index.c b/src/backend/catalog/index.c index b86ad73c626..bac8d527ae5 100644 --- a/src/backend/catalog/index.c +++ b/src/backend/catalog/index.c @@ -715,6 +715,9 @@ UpdateIndexRelation(Oid indexoid, * already exists. * INDEX_CREATE_PARTITIONED: * create a partitioned index (table must be partitioned) + * INDEX_CREATE_REPORT_PROGRESS: + * update the backend's progress information during index build. + * constr_flags: flags passed to index_constraint_create * (only if INDEX_CREATE_ADD_CONSTRAINT is set) * allow_system_table_mods: allow table to be a system catalog @@ -760,6 +763,7 @@ index_create(Relation heapRelation, bool invalid = (flags & INDEX_CREATE_INVALID) != 0; bool concurrent = (flags & INDEX_CREATE_CONCURRENT) != 0; bool partitioned = (flags & INDEX_CREATE_PARTITIONED) != 0; + bool progress = (flags & INDEX_CREATE_REPORT_PROGRESS) != 0; char relkind; TransactionId relfrozenxid; MultiXactId relminmxid; @@ -1276,7 +1280,8 @@ index_create(Relation heapRelation, } else { - index_build(heapRelation, indexRelation, indexInfo, false, true); + index_build(heapRelation, indexRelation, indexInfo, false, true, + progress); } /* @@ -1438,6 +1443,12 @@ index_create_copy(Relation heapRelation, bool concurrently, stattargets[i].isnull = isnull; } + /* + * Note: The current callers do not need INDEX_CREATE_REPORT_PROGRESS.

Second, REPACK (CONCURRENTLY) should not set PROGRESS_REPACK_PHASE to PROGRESS_REPACK_PHASE_FINAL_CLEANUP in rebuild_relation() because it calls finish_heap_swap() anyway (via rebuild_relation_finish_concurrent()), which does the same thing. --- src/backend/bootstrap/bootstrap.c | 2 +- src/backend/catalog/heap.c | 3 ++- src/backend/catalog/index.c | 22 ++++++++++++++++++---- src/backend/catalog/toasting.c | 3 ++- src/backend/commands/indexcmds.c | 1 + src/include/catalog/index.h | 4 +++- 6 files changed, 27 insertions(+), 8 deletions(-) diff --git a/src/backend/bootstrap/bootstrap.c b/src/backend/bootstrap/bootstrap.c index 38ef683d4c7..60fb7051830 100644 --- a/src/backend/bootstrap/bootstrap.c +++ b/src/backend/bootstrap/bootstrap.c @@ -1183,7 +1183,7 @@ build_indices(void) heap = table_open(ILHead->il_heap, NoLock); ind = index_open(ILHead->il_ind, NoLock); - index_build(heap, ind, ILHead->il_info, false, false); + index_build(heap, ind, ILHead->il_info, false, false, false); index_close(ind, NoLock); table_close(heap, NoLock); diff --git a/src/backend/catalog/heap.c b/src/backend/catalog/heap.c index 5748aa9a1a9..ae6b7cda3dd 100644 --- a/src/backend/catalog/heap.c +++ b/src/backend/catalog/heap.c @@ -3570,7 +3570,8 @@ RelationTruncateIndexes(Relation heapRelation) /* Initialize the index and rebuild */ /* Note: we do not need to re-establish pkey setting */ - index_build(heapRelation, currentIndex, indexInfo, true, false); + index_build(heapRelation, currentIndex, indexInfo, true, false, + true); /* We're done with this index */ index_close(currentIndex, NoLock); diff --git a/src/backend/catalog/index.c b/src/backend/catalog/index.c index e418d67e8e4..4b8ed2c7660 100644 --- a/src/backend/catalog/index.c +++ b/src/backend/catalog/index.c @@ -715,6 +715,9 @@ UpdateIndexRelation(Oid indexoid, * already exists. * INDEX_CREATE_PARTITIONED: * create a partitioned index (table must be partitioned) + * INDEX_CREATE_REPORT_PROGRESS: + * update the backend's progress information during index build. + * constr_flags: flags passed to index_constraint_create * (only if INDEX_CREATE_ADD_CONSTRAINT is set) * allow_system_table_mods: allow table to be a system catalog @@ -760,6 +763,7 @@ index_create(Relation heapRelation, bool invalid = (flags & INDEX_CREATE_INVALID) != 0; bool concurrent = (flags & INDEX_CREATE_CONCURRENT) != 0; bool partitioned = (flags & INDEX_CREATE_PARTITIONED) != 0; + bool progress = (flags & INDEX_CREATE_REPORT_PROGRESS) != 0; char relkind; TransactionId relfrozenxid; MultiXactId relminmxid; @@ -1276,7 +1280,8 @@ index_create(Relation heapRelation, } else { - index_build(heapRelation, indexRelation, indexInfo, false, true); + index_build(heapRelation, indexRelation, indexInfo, false, true, + progress); } /* @@ -1448,6 +1453,12 @@ index_create_copy(Relation heapRelation, bool concurrently, stattargets[i].isnull = isnull; } + /* + * Note: The current callers do not need INDEX_CREATE_REPORT_PROGRESS.

Second, REPACK (CONCURRENTLY) should not set PROGRESS_REPACK_PHASE to PROGRESS_REPACK_PHASE_FINAL_CLEANUP in rebuild_relation() because it calls finish_heap_swap() anyway (via rebuild_relation_finish_concurrent()), which does the same thing. --- src/backend/bootstrap/bootstrap.c | 2 +- src/backend/catalog/heap.c | 3 ++- src/backend/catalog/index.c | 26 +++++++++++++++++++++----- src/backend/catalog/toasting.c | 3 ++- src/include/catalog/index.h | 4 +++- 5 files changed, 29 insertions(+), 9 deletions(-) diff --git a/src/backend/bootstrap/bootstrap.c b/src/backend/bootstrap/bootstrap.c index c52c0a6023d..ebd41176b94 100644 --- a/src/backend/bootstrap/bootstrap.c +++ b/src/backend/bootstrap/bootstrap.c @@ -1184,7 +1184,7 @@ build_indices(void) heap = table_open(ILHead->il_heap, NoLock); ind = index_open(ILHead->il_ind, NoLock); - index_build(heap, ind, ILHead->il_info, false, false); + index_build(heap, ind, ILHead->il_info, false, false, false); index_close(ind, NoLock); table_close(heap, NoLock); diff --git a/src/backend/catalog/heap.c b/src/backend/catalog/heap.c index 5748aa9a1a9..ae6b7cda3dd 100644 --- a/src/backend/catalog/heap.c +++ b/src/backend/catalog/heap.c @@ -3570,7 +3570,8 @@ RelationTruncateIndexes(Relation heapRelation) /* Initialize the index and rebuild */ /* Note: we do not need to re-establish pkey setting */ - index_build(heapRelation, currentIndex, indexInfo, true, false); + index_build(heapRelation, currentIndex, indexInfo, true, false, + true); /* We're done with this index */ index_close(currentIndex, NoLock); diff --git a/src/backend/catalog/index.c b/src/backend/catalog/index.c index e418d67e8e4..36712b1bcc2 100644 --- a/src/backend/catalog/index.c +++ b/src/backend/catalog/index.c @@ -715,6 +715,9 @@ UpdateIndexRelation(Oid indexoid, * already exists. * INDEX_CREATE_PARTITIONED: * create a partitioned index (table must be partitioned) + * INDEX_CREATE_SUPPRESS_PROGRESS: + * don't report progress during the index build. + * * constr_flags: flags passed to index_constraint_create * (only if INDEX_CREATE_ADD_CONSTRAINT is set) * allow_system_table_mods: allow table to be a system catalog @@ -760,6 +763,7 @@ index_create(Relation heapRelation, bool invalid = (flags & INDEX_CREATE_INVALID) != 0; bool concurrent = (flags & INDEX_CREATE_CONCURRENT) != 0; bool partitioned = (flags & INDEX_CREATE_PARTITIONED) != 0; + bool progress = (flags & INDEX_CREATE_SUPPRESS_PROGRESS) == 0; char relkind; TransactionId relfrozenxid; MultiXactId relminmxid; @@ -1276,7 +1280,8 @@ index_create(Relation heapRelation, } else { - index_build(heapRelation, indexRelation, indexInfo, false, true); + index_build(heapRelation, indexRelation, indexInfo, false, true, + progress); } /* @@ -1448,8 +1453,16 @@ index_create_copy(Relation heapRelation, bool concurrently, stattargets[i].isnull = isnull; } + /* + * The current callers do not need to report progress: if 'concurrently' + * is true, there is no build at all to report about; and otherwise the + * index build is a sub-command of REPACK, and the current progress + * reporting infrastructure does not allow two commands to report their + * progress at the same time. + */ if (concurrently) - flags = INDEX_CREATE_SKIP_BUILD | INDEX_CREATE_CONCURRENT; + flags = INDEX_CREATE_SKIP_BUILD | INDEX_CREATE_CONCURRENT | + INDEX_CREATE_SUPPRESS_PROGRESS; /* * Now create the new index. @@ -1538,7 +1551,7 @@ index_concurrently_build(Oid heapRelationId, indexInfo->ii_BrokenHotChain = false; /* Now build the index */ - index_build(heapRel, indexRelation, indexInfo, false, true); + index_build(heapRel, indexRelation, indexInfo, false, true, true); /* Roll back any GUC changes executed by index functions */ AtEOXact_GUC(false, save_nestlevel); @@ -3009,6 +3022,7 @@ index_update_stats(Relation rel, * * isreindex indicates we are recreating a previously-existing index. * parallel indicates if parallelism may be useful. + * progress indicates if the backend should update its progress info. * * Note: before Postgres 8.2, the passed-in heap and index Relations * were automatically closed by this routine.
