I suppose it's a bit late to be answering this now, but it sounds like
you've got a corrupted database, which is something that can have many
causes.

Generally, the way people handle problems like the one you have in
practice is to do enough surgery on the catalogs to make pg_dump work,
and then restore into a freshly created database.
