Hi Team,

For last 2 days we are facing issue with replication.

WARNING:  page 21 of relation base/1193555/19384612 does not exist
CONTEXT:  xlog redo insert: rel 1663/1193555/19384612; tid 21/1
PANIC:  WAL contains references to invalid pages
CONTEXT:  xlog redo insert: rel 1663/1193555/19384612; tid 21/1
LOG:  startup process (PID 20622) was terminated by signal 6: Aborted
LOG:  terminating any other active server processes

Stand by server went down with this error.

we just using warm stand by, but we enabled wal_level as 'hot_stanndby' in Master server. 

I just read this mailing list, and in postgres 9.2.7 we have fix,

But as of now,
if i change the wal level as archive, then this problem will go..? We are just using warm stand by. so shall we change the wal_level as archive..? Can you please reply this mail as soon as possible?

AFAIK, the problem appears when hot_standby is set on, so you need to
turn it off. Also, take a look at the link below:
