Hmm, what PG version is that? This looks a bit like the results of some
bugs that were fixed awhile ago.

Well, if you don't have a recent backup to go back to, you can try
pg_resetxlog, but it's anyone's guess how consistent the database
will be afterwards. A dump/initdb/restore sequence would be a good
idea. And if you aren't on the latest release in whatever branch
you are using, now would be a good time to update.
