From 1b1e335b15e19a89601d3b025b4d3deb60b39f98 Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Thu, 1 May 2008 19:55:40 +0000 Subject: [PATCH] Make the minimum allowed value of work_mem be 64KB always, rather than having it vary with BLCKSZ as before. This agrees with what the documentation says, and avoids a regression test problem when BLCKSZ is larger than default.
