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/executor/spi.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) (limited to 'src/backend/executor/spi.c') diff --git a/src/backend/executor/spi.c b/src/backend/executor/spi.c index cde9ab6ff6e..f39c481db93 100644 --- a/src/backend/executor/spi.c +++ b/src/backend/executor/spi.c @@ -8,7 +8,7 @@ * * * IDENTIFICATION - * $Header: /cvsroot/pgsql/src/backend/executor/spi.c,v 1.80 2002/12/15 16:17:46 tgl Exp $ + * $Header: /cvsroot/pgsql/src/backend/executor/spi.c,v 1.81 2002/12/15 21:01:34 tgl Exp $ * *------------------------------------------------------------------------- */ @@ -1489,9 +1489,9 @@ _SPI_copy_plan(_SPI_plan *plan, int location) */ plancxt = AllocSetContextCreate(parentcxt, "SPI Plan", - 1024, - 1024, - ALLOCSET_DEFAULT_MAXSIZE); + ALLOCSET_SMALL_MINSIZE, + ALLOCSET_SMALL_INITSIZE, + ALLOCSET_SMALL_MAXSIZE); oldcxt = MemoryContextSwitchTo(plancxt); /* Copy the SPI plan into its own context */ -- cgit v1.2.3
