Stop the cluster, start a single-user session ("postgres --single"),
re-grant superuser to the postgres user and/or whatever else you
wish you could take back, end that session, restart the cluster.

(You're not the first to mess up like this.)

Tom, your knowledge is vast and your advice is extremely useful. Have you ever considered creating a dedicated page for beginners? Something like AskTom.postgresql.org would probably be appropriate.
