I have had similar troubles, related to oid overflow. I had to modify pg_dump
to properly cast queries that contain oids. This is against 7.1.3 source. The
patch was hacked quickly, in order to get a corrupted database reloaded, and
this while I was traveling in another country... so it is far from perfect but
saved my database(s). It also fixes other oid-related troubles of pg_dump.
See attached file.
