From d9384a4b7334ba755db88160fb96cd33725bd6d3 Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Sun, 9 Mar 2008 04:56:28 +0000 Subject: Remove postmaster.c's check that NBuffers is at least twice MaxBackends. With the addition of multiple autovacuum workers, our choices were to delete the check, document the interaction with autovacuum_max_workers, or complicate the check to try to hide that interaction. Since this restriction has never been adequate to ensure backends can't run out of pinnable buffers, it doesn't really have enough excuse to live to justify the second or third choices. Per discussion of a complaint from Andreas Kling (see also bug #3888). This commit also removes several documentation references to this restriction, but I'm not sure I got them all. --- doc/src/sgml/config.sgml | 5 ++--- 1 file changed, 2 insertions(+), 3 deletions(-) (limited to 'doc/src') diff --git a/doc/src/sgml/config.sgml b/doc/src/sgml/config.sgml index 2e8d62e2923..677fd4d7bf5 100644 --- a/doc/src/sgml/config.sgml +++ b/doc/src/sgml/config.sgml @@ -1,4 +1,4 @@ - + Server Configuration @@ -736,8 +736,7 @@ SET ENABLE_SEQSCAN TO OFF; memory buffers.
