From 401de9c8bef9c77dd25ba6c111094bba14d470d8 Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Thu, 30 Jun 2005 00:00:52 +0000 Subject: Improve the checkpoint signaling mechanism so that the bgwriter can tell the difference between checkpoints forced due to WAL segment consumption and checkpoints forced for other reasons (such as CREATE DATABASE). Avoid generating 'checkpoints are occurring too frequently' messages when the checkpoint wasn't caused by WAL segment consumption. Per gripe from Chris K-L. --- src/backend/access/transam/xlog.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'src/backend/access/transam/xlog.c') diff --git a/src/backend/access/transam/xlog.c b/src/backend/access/transam/xlog.c index 93f8d75e6cc..4c2f6a69a70 100644 --- a/src/backend/access/transam/xlog.c +++ b/src/backend/access/transam/xlog.c @@ -7,7 +7,7 @@ * Portions Copyright (c) 1996-2005, PostgreSQL Global Development Group * Portions Copyright (c) 1994, Regents of the University of California * - * $PostgreSQL: pgsql/src/backend/access/transam/xlog.c,v 1.204 2005/06/29 22:51:53 tgl Exp $ + * $PostgreSQL: pgsql/src/backend/access/transam/xlog.c,v 1.205 2005/06/30 00:00:50 tgl Exp $ * *------------------------------------------------------------------------- */ @@ -1337,7 +1337,7 @@ XLogWrite(XLogwrtRqst WriteRqst) if (XLOG_DEBUG) elog(LOG, "time for a checkpoint, signaling bgwriter"); #endif - RequestCheckpoint(false); + RequestCheckpoint(false, true); } } } @@ -5496,7 +5496,7 @@ pg_start_backup(PG_FUNCTION_ARGS) * will have different checkpoint positions and hence different * history file names, even if nothing happened in between. */ - RequestCheckpoint(true); + RequestCheckpoint(true, false); /* * Now we need to fetch the checkpoint record location, and also its -- cgit v1.2.3
