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

pg_resetxlog does the trick and db can be started and readable.
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.
