If you are using 7.2, shut down the postmaster, start a standalone
backend and issue the proper ALTER USER commands to restore postgres'
superuserdom. (There is info about running a standalone backend on
the 'postgres' man page and the 'REINDEX' man page.)
In prior releases I think you may be out of luck, unless you want to
risk manual surgery on the pg_shadow file.
