From 229bffedbc52f12aadb95ca2ee24d5bef36b7c7d Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Tue, 6 Jan 2009 15:51:38 +0000 Subject: [PATCH] Revert the default toast compression strategy to the former behavior where there's no limit on the size of datum we'll try to compress. Other 8.4 tweaks to the behavior remain in place.
