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: checkpoint record is at 41E/BF2D5DC0

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
