Hello everybody,

This weeked both replicas of our main db crashed at the same time with this
error :

2014-02-09 11:42:51 GMT    0 52c671da.14da - PANIC:  WAL contains references
to invalid pages
2014-02-09 11:42:51 GMT    0 52c671da.14da - CONTEXT:  xlog redo vacuum: rel

2014-02-09 11:42:52 GMT    0 52c671d9.14d1 - LOG:  startup process (PID
5338) was terminated by signal 6: Aborted
2014-02-09 11:42:52 GMT    0 52c671d9.14d1 - LOG:  terminating any other
active server processes


All three servers (main + two replicas) are on v. 9.3.2 running on Centos
6.4

We upgraded one month ago the main db from v 9.2.6 to 9.3.2 through
pg_upgrade and had the replicas rebuilt on 9.3.2

I searched the mailing lists and found someone that had the same problem in
the past but it seems that their problem was fixed by already released
patches.

( see thread
http://www.postgresql.org/message-id/675b7cee-b7f0-4e32-8e34-1efaf3ca5fe9@email.android.com)

So it seems that our problem is a new one since we are running the latest
version…….

Thank you for your help

Marco
