Re: Recovering database after disk crash

After doing some more reading I've come to the conclusion that I'm in
completely over my head. I got a fresh copy of the corrupt data and
am starting from the very beginning. Here's the error I get on
startup:

I ran pg_resetxlog in my previous mucking around, but that's when all
hell broke loose, so I'm holding off until someone more qualified
advises me to do so.

TIA
