Glad to hear that you can spin up the database and get to your data.
Sorry to hear that you did end up losing data on that server.

We pretty much lost the data for the last two days, but
since our postgresql wereN'T running well, it is fewer than it

pg_resetxlog does the trick and db can be started and

I am dumping the data out and import to a newly created
database cluster.

Thanks a lot for the help.
Sounds
like you have a corrupt wal files that you will
have to reset the
wal logs with pgresetxlog.
http://www.postgresql.org/docs/8.2/static/app-pgresetxlog.html
This will result in missing transactions so before
you do this shutdown
postgres and make a copy of the database files
first. That way if you
don't like what happens you can always go back to
the way things were.
Also right now would be a good time to evaluate
your backup strategy,
which is a different topic for a different thread,
but I can certainly
help with that as well.
