You've definitely got some problems in the pg_attribute catalog.
If you are lucky, reindexing pg_attribute will get you out of this.
Otherwise it's time to initdb and reload (or at least drop that one
database, recreate it, reload it). I wouldn't trust half measures such
as dropping the one known-corrupt table, because the odds are that more
rows in pg_attribute got hit than just the ones reported in the first
failure.
