From 2730eb9ae4f9483a18cbc6168c651318b717c37f Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Thu, 13 Jan 2005 23:07:34 +0000 Subject: [PATCH] Change exec_eval_simple_expr's param list allocation call from MemoryContextAllocZero back to MemoryContextAlloc, same as it was in 7.4. The zeroing is unnecessary since all the meaningful fields are filled in just below. I had made it do that out of neatnik-ism, but some testing with an example provided by Pavel Stehule showed that the zeroing was accounting for about 5% of the runtime in a compute-intensive plpgsql function. That seems a bit high of a price for neatnik-ism... --- src/pl/plpgsql/src/pl_exec.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/src/pl/plpgsql/src/pl_exec.c b/src/pl/plpgsql/src/pl_exec.c index 90dfc3c0d1..bd2c6a00be 100644 --- a/src/pl/plpgsql/src/pl_exec.c +++ b/src/pl/plpgsql/src/pl_exec.c @@ -3,7 +3,7 @@ * procedural language * * IDENTIFICATION - * $PostgreSQL: pgsql/src/pl/plpgsql/src/pl_exec.c,v 1.126 2004/12/21 18:33:35 tgl Exp $ + * $PostgreSQL: pgsql/src/pl/plpgsql/src/pl_exec.c,v 1.127 2005/01/13 23:07:34 tgl Exp $ * * This software is copyrighted by Jan Wieck - Hamburg. * @@ -3606,7 +3606,7 @@ exec_eval_simple_expr(PLpgSQL_execstate *estate, * have more than one active param list. */ paramLI = (ParamListInfo) - MemoryContextAllocZero(econtext->ecxt_per_tuple_memory, + MemoryContextAlloc(econtext->ecxt_per_tuple_memory, (expr->nparams + 1) * sizeof(ParamListInfoData)); /* -- 2.11.0
