From 3efba16d569ef00f8db20eb7c1f3ac80140e5902 Mon Sep 17 00:00:00 2001 From: Heikki Linnakangas Date: Tue, 27 Apr 2010 09:25:18 +0000 Subject: [PATCH] If a base backup is cancelled by server shutdown or crash, throw an error in WAL recovery when it sees the shutdown checkpoint record. It's more user-friendly to find out about it at that point than at the end of recovery, and you're not left wondering why your hot standby server never opens up for read-only connections. --- src/backend/access/transam/xlog.c | 12 +++++++++++- 1 file changed, 11 insertions(+), 1 deletion(-) diff --git a/src/backend/access/transam/xlog.c b/src/backend/access/transam/xlog.c index 3f339825ae..6812cf5e9a 100644 --- a/src/backend/access/transam/xlog.c +++ b/src/backend/access/transam/xlog.c @@ -7,7 +7,7 @@ * Portions Copyright (c) 1996-2010, PostgreSQL Global Development Group * Portions Copyright (c) 1994, Regents of the University of California * - * $PostgreSQL: pgsql/src/backend/access/transam/xlog.c,v 1.403 2010/04/23 20:21:31 sriggs Exp $ + * $PostgreSQL: pgsql/src/backend/access/transam/xlog.c,v 1.404 2010/04/27 09:25:18 heikki Exp $ * *------------------------------------------------------------------------- */ @@ -7713,6 +7713,16 @@ xlog_redo(XLogRecPtr lsn, XLogRecord *record) if (standbyState != STANDBY_DISABLED) CheckRequiredParameterValues(checkPoint); + /* + * If we see a shutdown checkpoint while waiting for an + * end-of-backup record, the backup was cancelled and the + * end-of-backup record will never arrive. + */ + if (InArchiveRecovery && + !XLogRecPtrIsInvalid(ControlFile->backupStartPoint)) + ereport(ERROR, + (errmsg("online backup was cancelled, recovery cannot continue"))); + /* * If we see a shutdown checkpoint, we know that nothing was * running on the master at this point.
