How large is pg_log? If it's 1Gb in size or nearly that, then your
problem is that the transaction counter wrapped around. I believe that
a couple of people have gotten out of such a fix by resetting the
counter to a few hundred transactions less than 4G, giving them time to
pg_dump before it wraps again. I don't remember how to do it in such a
prehistoric version of Postgres, though. Check the archives.
