Moreover, the problem is that if you have database owners that are not
superusers, they can't easily fix the issue themselves.  Since the
public schema is owned by postgres, they database owner can't just go in
and run GRANT CREATE ON SCHEMA PUBLIC TO whomever to restore the old
behavior or grant specific access.  It would be simpler if we didn't
install a public schema by default at all.
