Hot standby 9.2.1 PANIC: WAL contains references to invalid pages

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?
