[PATCH v2 3/4] Add alias to be used as "unset" state. 178+ messages / 2 participants [nested] [flat]
* [PATCH v2 3/4] Add alias to be used as "unset" state. @ 2025-09-04 16:22 Nikolay Shaplov <[email protected]> 0 siblings, 0 replies; 178+ messages in thread From: Nikolay Shaplov @ 2025-09-04 16:22 UTC (permalink / raw) Add `unset_alias` string parameter to ternary reloption definition. This will allow user explicitly switch ternary option to "unset" state. Use this feature to implement `vacuum_index_cleanup` and gist's `buffering` reloptions as ternary reloptions --- src/backend/access/common/reloptions.c | 91 +++++++++++--------------- src/backend/access/gist/gistbuild.c | 4 +- src/backend/commands/vacuum.c | 11 ++-- src/include/access/gist_private.h | 10 +-- src/include/access/reloptions.h | 7 +- src/include/utils/rel.h | 10 +-- src/test/regress/expected/gist.out | 3 +- 7 files changed, 54 insertions(+), 82 deletions(-) diff --git a/src/backend/access/common/reloptions.c b/src/backend/access/common/reloptions.c index f543f11001..3637646641 100644 --- a/src/backend/access/common/reloptions.c +++ b/src/backend/access/common/reloptions.c @@ -170,6 +170,27 @@ static relopt_ternary ternaryRelOpts[] = RELOPT_KIND_HEAP | RELOPT_KIND_TOAST, ShareUpdateExclusiveLock }, + NULL, + TERNARY_UNSET + }, + { + { + "vacuum_index_cleanup", + "Controls index vacuuming and index cleanup", + RELOPT_KIND_HEAP | RELOPT_KIND_TOAST, + ShareUpdateExclusiveLock + }, + "auto", + TERNARY_UNSET + }, + { + { + "buffering", + "Enables buffering build for this GiST index", + RELOPT_KIND_GIST, + AccessExclusiveLock + }, + "auto", TERNARY_UNSET }, /* list terminator */ @@ -489,30 +510,6 @@ static relopt_real realRelOpts[] = {{NULL}} }; -/* values from StdRdOptIndexCleanup */ -static relopt_enum_elt_def StdRdOptIndexCleanupValues[] = -{ - {"auto", STDRD_OPTION_VACUUM_INDEX_CLEANUP_AUTO}, - {"on", STDRD_OPTION_VACUUM_INDEX_CLEANUP_ON}, - {"off", STDRD_OPTION_VACUUM_INDEX_CLEANUP_OFF}, - {"true", STDRD_OPTION_VACUUM_INDEX_CLEANUP_ON}, - {"false", STDRD_OPTION_VACUUM_INDEX_CLEANUP_OFF}, - {"yes", STDRD_OPTION_VACUUM_INDEX_CLEANUP_ON}, - {"no", STDRD_OPTION_VACUUM_INDEX_CLEANUP_OFF}, - {"1", STDRD_OPTION_VACUUM_INDEX_CLEANUP_ON}, - {"0", STDRD_OPTION_VACUUM_INDEX_CLEANUP_OFF}, - {(const char *) NULL} /* list terminator */ -}; - -/* values from GistOptBufferingMode */ -static relopt_enum_elt_def gistBufferingOptValues[] = -{ - {"auto", GIST_OPTION_BUFFERING_AUTO}, - {"on", GIST_OPTION_BUFFERING_ON}, - {"off", GIST_OPTION_BUFFERING_OFF}, - {(const char *) NULL} /* list terminator */ -}; - /* values from ViewOptCheckOption */ static relopt_enum_elt_def viewCheckOptValues[] = { @@ -524,28 +521,6 @@ static relopt_enum_elt_def viewCheckOptValues[] = static relopt_enum enumRelOpts[] = { - { - { - "vacuum_index_cleanup", - "Controls index vacuuming and index cleanup", - RELOPT_KIND_HEAP | RELOPT_KIND_TOAST, - ShareUpdateExclusiveLock - }, - StdRdOptIndexCleanupValues, - STDRD_OPTION_VACUUM_INDEX_CLEANUP_AUTO, - gettext_noop("Valid values are \"on\", \"off\", and \"auto\".") - }, - { - { - "buffering", - "Enables buffering build for this GiST index", - RELOPT_KIND_GIST, - AccessExclusiveLock - }, - gistBufferingOptValues, - GIST_OPTION_BUFFERING_AUTO, - gettext_noop("Valid values are \"on\", \"off\", and \"auto\".") - }, { { "check_option", @@ -913,13 +888,14 @@ add_local_bool_reloption(local_relopts *relopts, const char *name, */ static relopt_ternary * init_ternary_reloption(bits32 kinds, const char *name, const char *desc, - ternary default_val, LOCKMODE lockmode) + ternary default_val, const char* unset_alias, LOCKMODE lockmode) { relopt_ternary *newoption; newoption = (relopt_ternary *) allocate_reloption(kinds, RELOPT_TYPE_TERNARY, name, desc, lockmode); newoption->default_val = default_val; + newoption->unset_alias = unset_alias; return newoption; } @@ -930,10 +906,10 @@ init_ternary_reloption(bits32 kinds, const char *name, const char *desc, */ void add_ternary_reloption(bits32 kinds, const char *name, const char *desc, - ternary default_val, LOCKMODE lockmode) + ternary default_val, const char* unset_alias, LOCKMODE lockmode) { relopt_ternary *newoption = init_ternary_reloption(kinds, name, desc, - default_val, lockmode); + default_val, unset_alias, lockmode); add_reloption((relopt_gen *) newoption); } @@ -947,11 +923,11 @@ add_ternary_reloption(bits32 kinds, const char *name, const char *desc, void add_local_ternary_reloption(local_relopts *relopts, const char *name, const char *desc, ternary default_val, - int offset) + const char* unset_alias, int offset) { relopt_ternary *newoption = init_ternary_reloption(RELOPT_KIND_LOCAL, name, desc, - default_val, 0); + default_val, unset_alias, 0); add_local_reloption(relopts, (relopt_gen *) newoption, offset); } @@ -1692,8 +1668,19 @@ parse_one_reloption(relopt_value *option, char *text_str, int text_len, case RELOPT_TYPE_TERNARY: { bool b; + relopt_ternary *opt = (relopt_ternary *) option->gen; + parsed = parse_bool(value, &b); option->values.ternary_val = b ?
