I see you've resolved your problem, but for future reference, note that
you could have gotten a more detailed error message if you'd issued the
DROP USER while connected to the postgres database. When the command
is issued in database A, we can't see the details of what the user owns
in database B, only that there is something over there :-(

FWIW, I'm guessing that the issue was not object ownership per se,
but permissions granted on some object owned by someone else. Those
have to be revoked as well before a DROP USER will succeed.

You might also care to read up on DROP OWNED BY.
