* [PATCH 1/5] Refactor index_concurrently_create_copy() for use with REPACK (CONCURRENTLY). @ 2026-03-11 13:15 Antonin Houska <[email protected]> 0 siblings, 0 replies; 2+ messages in thread From: Antonin Houska @ 2026-03-11 13:15 UTC (permalink / raw) This patch moves the code to index_create_copy() and adds a "concurrently" parameter so it can be used by REPACK (CONCURRENTLY). With the CONCURRENTLY option, REPACK cannot simply swap the heap file and rebuild its indexes. Instead, it needs to build a separate set of indexes (including system catalog entries) *before* the actual swap, to reduce the time AccessExclusiveLock needs to be held for. --- src/backend/catalog/index.c | 54 +++++++++++++++++++++++--------- src/backend/commands/indexcmds.c | 6 ++-- src/backend/nodes/makefuncs.c | 9 +++--- src/include/catalog/index.h | 3 ++ src/include/nodes/makefuncs.h | 4 ++- 5 files changed, 54 insertions(+), 22 deletions(-) diff --git a/src/backend/catalog/index.c b/src/backend/catalog/index.c index 5ee6389d39c..f8e6c3d804e 100644 --- a/src/backend/catalog/index.c +++ b/src/backend/catalog/index.c @@ -1288,15 +1288,32 @@ index_create(Relation heapRelation, /* * index_concurrently_create_copy * - * Create concurrently an index based on the definition of the one provided by - * caller.
