Hi
It may be PG9.2.x on HA cluster(pgsql RA on Pacemaker).
This is known bug.
When HA cluster starting, PG use recovery.conf in crash recovery.
But using recovery.conf in PG9.2, PG need database cluster that does not be crashed.
Please read under following mailing list.
[HACKERS] [BUG?] lag of minRecoveryPont in archive recovery
[BUGS] PITR potentially broken in 9.2
Latest-dev(next release version 9.2.3)is fixed this bug.

Except in my case no number of restarts helped. You didn't say, were
you explicitly copying $PGDATA or using some other mechanism to
migrate the data elsewhere?
Also, which version of postgres are you using?

Hi Everyone,
So we had to failover and do a full base backup to get our slave database
back online and ran into a interesting scenario. After copying the data
directory, setting up the recovery.conf, and starting the slave database,
the database crashes while replaying xlogs. However, trying to start the
database again, the database is able to replay xlogs farther than it
initially got, but ultimately ended up failing out again. After starting the
DB a third time, PostgreSQL replays even further and catches up to the
master to start streaming replication. Is this common and or acceptable?
The error messages that cause PostgreSQL to stop replaying xlogs:

Fortunately, these errors only pertain to indexes, which can be rebuilt.
But is this a sign that the data directory on the slave is corrupt?
