From 77a7e9968bf109d11b87c40ba41d4b1a7f1d28ea Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Mon, 12 Aug 2002 00:36:12 +0000 Subject: Change memory-space accounting mechanism in tuplesort.c and tuplestore.c to make a reasonable attempt at accounting for palloc overhead, not just the requested size of each memory chunk. Since in many scenarios this will make for a significant reduction in the amount of space acquired, partially compensate by doubling the default value of SORT_MEM to 1Mb.
