Hmm - I believe that means a data/index block was corrupted.


indices were recreated (reindex table), so i think this is data related problem.
 

Have you seen any crashes, or hardware-related errors in your logs?


nope. uptime is over 40 days.

the machine is not used for anything else so i can't tell anything, but i didn't see any problems with it.


What are your config settings, particularly the first three here:
   http://www.postgresql.org/docs/8.1/static/runtime-config-wal.html
fsync, wal_sync_method, full_page_writes

sure:
irr=# show fsync;
 fsync
-------
 on
(1 row)

irr=# show wal_sync_method;
 wal_sync_method
-----------------
 fdatasync
(1 row)

irr=# show full_page_writes;
 full_page_writes
------------------
 on
(1 row)
