From 4ee5c40b06f098910ed0fc5fd72fb2744776ccbb Mon Sep 17 00:00:00 2001 From: Alvaro Herrera Date: Wed, 7 Nov 2012 16:23:39 -0300 Subject: [PATCH] Don't try to use a unopened relation Commit 4c9d0901 mistakenly introduced a call to TransferPredicateLocksToHeapRelation() on an index relation that had been closed a few lines above. Moving up an index_open() call that's below is enough to fix the problem. Discovered by me while testing an unrelated patch. --- src/backend/catalog/index.c | 5 ++--- 1 file changed, 2 insertions(+), 3 deletions(-) diff --git a/src/backend/catalog/index.c b/src/backend/catalog/index.c index 756f6d918b..d2d91c1b78 100644 --- a/src/backend/catalog/index.c +++ b/src/backend/catalog/index.c @@ -1475,6 +1475,8 @@ index_drop(Oid indexId, bool concurrent) * conflicts with existing predicate locks, so now is the time to move * them to the heap relation. */ + userHeapRelation = heap_open(heapId, ShareUpdateExclusiveLock); + userIndexRelation = index_open(indexId, ShareUpdateExclusiveLock); TransferPredicateLocksToHeapRelation(userIndexRelation); /* @@ -1484,9 +1486,6 @@ index_drop(Oid indexId, bool concurrent) */ indexRelation = heap_open(IndexRelationId, RowExclusiveLock); - userHeapRelation = heap_open(heapId, ShareUpdateExclusiveLock); - userIndexRelation = index_open(indexId, ShareUpdateExclusiveLock); - tuple = SearchSysCacheCopy1(INDEXRELID, ObjectIdGetDatum(indexId)); if (!HeapTupleIsValid(tuple)) -- 2.40.0
