What process did you use for setting up the slave?
There's a fix awaiting release in 9.2.4 that might explain data
corruption on a slave, depending on how it was set up:
* Ensure we do crash recovery before entering archive recovery,
if the database was not stopped cleanly and a recovery.conf file
is present (Heikki Linnakangas, Kyotaro Horiguchi, Mitsumasa Kondo)
This is needed to ensure that the database is consistent in certain
scenarios, such as initializing a standby server with a filesystem
snapshot from a running server.
This theory would be more probable if it's a relatively new slave, since
any corruption would have been there in the slave's initial state, just
waiting for the replay to run into it.
