Hi Derek,
Oh, that's definitely not good.
It sounds like some kind of corruption has occured to your database, or
that someone has deleted (maybe accidentally) the pg_users table.
Is there any chance that your server (or even just PostgreSQL) has
crashed since the last time you used psql?
Regards and best wishes,
Justin Clift
