It turns out it was a bad sector, and once the data was retreived and the
drive replaced, postgres was able to go through the startup process
sucessfully. Given that it did not report any errors on recovery, I suppose
there was no data loss, but even if there was some damage to the log file, it
should be minor - the crash happened at 6am, almost no activity, so I'm not
going to worry about that at all at this point.
Anyway, thank you very much for your help.
One quick question - you mentioned I should upgrade to 7.1.3 beofre I run
vacuum again. What are the known problems that "ask" for this?
Thanks again!
