Database Startup Failure: FATAL: could not read block 6 of relation 16390/16391/5153282: Success
Hi,
I have been asked to help recover a database that seems to have been corrupted after a power failure.
This is what we see when psql tries to start up:

[2009-11-10 10:39:17 EST] LOG: logger shutting down
Does anyone have any clues how we might recover this database?
Also what does it mean by "Success" in the FATAL message? Seems a strange fatal error...
Thanks in advance,
Regards // Mike

What PG version is this exactly?

It's probably a read-past-EOF case.

Hi Tom,
Postgres is 8.2.3.
The owners of this database have now decided to rebuild it from scratch so please don't spend much more time on
answeringthis. Although, I'd like to know how to proceed in cases like this in case it ever happens again.
Regards // Mike

8.2.something-recent might have coped with this better; I notice
a couple of WAL replay bug fixes in the later release notes.
You should encourage an update ...
