From e64c7feb2fd80c89d2220cbe9e026a031f34509c Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Sun, 15 Dec 2002 21:01:34 +0000 Subject: Tweak default memory context allocation policy so that a context is not given any malloc block until something is first allocated in it; but thereafter, MemoryContextReset won't release that first malloc block. This preserves the quick-reset property of the original policy, without forcing 8K to be allocated to every context whether any of it is ever used or not. Also, remove some more no-longer-needed explicit freeing during ExecEndPlan. --- src/backend/commands/prepare.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) (limited to 'src/backend/commands/prepare.c') diff --git a/src/backend/commands/prepare.c b/src/backend/commands/prepare.c index ece9802dc41..19d64c3e1c7 100644 --- a/src/backend/commands/prepare.c +++ b/src/backend/commands/prepare.c @@ -6,7 +6,7 @@ * Copyright (c) 2002, PostgreSQL Global Development Group * * IDENTIFICATION - * $Header: /cvsroot/pgsql/src/backend/commands/prepare.c,v 1.11 2002/12/15 16:17:42 tgl Exp $ + * $Header: /cvsroot/pgsql/src/backend/commands/prepare.c,v 1.12 2002/12/15 21:01:34 tgl Exp $ * *------------------------------------------------------------------------- */ @@ -256,9 +256,9 @@ StoreQuery(const char *stmt_name, List *query_list, List *plan_list, /* Make a permanent memory context for the hashtable entry */ entrycxt = AllocSetContextCreate(TopMemoryContext, stmt_name, - 1024, - 1024, - ALLOCSET_DEFAULT_MAXSIZE); + ALLOCSET_SMALL_MINSIZE, + ALLOCSET_SMALL_INITSIZE, + ALLOCSET_SMALL_MAXSIZE); oldcxt = MemoryContextSwitchTo(entrycxt); -- cgit v1.2.3
