Hi.
I have this problem:
I have PostgreSQL 9.1.3 and the last night crash it.
This was the first error after an autovacuum (the night before last):
<2012-06-06 00:59:07 MDT 814 4fceffbb.32e >LOG: autovacuum: found

Last night it was terminated by signal 6.

And the only option was pg_resetxlog.
After this a lot of querys showed me this error:
<2012-06-07 09:24:22 MDT 1306 4fd0c7a6.51a >ERROR: missing chunk
number 0 for toast value 393330 in pg_toast_2619
<2012-06-07 09:24:31 MDT 1306 4fd0c7a6.51a >ERROR: missing chunk
number 0 for toast value 393332 in pg_toast_2619
I lost some databases.
I restarted the cluster again with initdb and then I restored the
databases that I could backup (for the other I restored an old backup)
no space or permissions problem. No filesystem or disk error.
Can you help me to know what happened?
Did you take a copy of the PostgreSQL data directory and error logs
before you tried to fix the problem, as per the advice here:
http://wiki.postgresql.org/wiki/Corruption
If you did, it might be possible to tell what happened. If you didn't
then you've probably destroyed the evidence needed to determine what
went wrong (and maybe recover some lost data).
