I was hoping someone else would jump in, but I see that your
previous post didn't copy the list, which solves *that* mystery.
I'm curious whether you might have enabled one of the "it's OK to
trash my database integrity to boost performance" options. (People
with enough replication often feel that this *is* OK.) Please run
the query on this page and post the results:
http://wiki.postgresql.org/wiki/Server_Configuration
Basically, if fsync or full_page_writes is turned off and there was
a crash, that explains it. If not, it provides more information to
proceed.
You might want to re-start the thread on pgsql-general, though. Not
everybody who might be able to help with a problem like this follows
the performance list. Or, if you didn't set any of the dangerous
configuration options, this sounds like a bug -- so pgsql-bugs might
be even better.
