What Postgres version are you running? (I suspect it must be pre-7.1.)
It would seem that something bad has happened to some rows in
pg_attribute. You might possibly be able to recover by reindexing
pg_attribute, but I'm not sure that REINDEX exists or is trustworthy
in whatever version you have. Probably the best advice is to try
to pg_dump your database, and if that's successful re-initdb and
reload. (You'd be well advised to update to 7.1.3 while you're at it.)
