From f8b629052e75835ab255bfa4e1ce6ada570fa9e2 Mon Sep 17 00:00:00 2001 From: Peter Eisentraut Date: Thu, 24 Aug 2023 08:26:13 +0200 Subject: [PATCH 1/3] Remove IndexInfo.ii_OpclassOptions field It is unnecessary to include this field in IndexInfo. It is only used by DDL code, not during execution. It is really only used to pass local information around between functions in index.c and indexcmds.c, for which it is clearer to use local variables, like in similar cases. --- src/backend/catalog/index.c | 31 ++++++++++++++----------------- src/backend/catalog/toasting.c | 3 +-- src/backend/commands/indexcmds.c | 30 +++++++++++++++++------------- src/backend/nodes/makefuncs.c | 3 --- src/include/catalog/index.h | 1 + src/include/nodes/execnodes.h | 1 - 6 files changed, 33 insertions(+), 36 deletions(-) diff --git a/src/backend/catalog/index.c b/src/backend/catalog/index.c index fd09378848..9b0cbd8979 100644 --- a/src/backend/catalog/index.c +++ b/src/backend/catalog/index.c @@ -721,6 +721,7 @@ index_create(Relation heapRelation, Oid tableSpaceId, const Oid *collationIds, const Oid *opclassIds, + const Datum *opclassOptions, const int16 *coloptions, Datum reloptions, bits16 flags, @@ -1016,7 +1017,7 @@ index_create(Relation heapRelation, /* * append ATTRIBUTE tuples for the index */ - AppendAttributeTuples(indexRelation, indexInfo->ii_OpclassOptions);
