Yeah, it's automatically there in a shadowy sort of way. Try this, for example, in your cluster with no PUBLIC role:
test=# revoke create on database test from public; REVOKE test=# grant select on pg_class to public; GRANT
well... surprisingly that works... does the public role exist in the SQL standard? why it is not in the pg_roles table?
