Prevent pg_ctl from being run as root. Since it uses configuration files
owned by postgres, doing "pg_ctl start" as root could allow a privilege
escalation attack, as pointed out by iDEFENSE. Of course the postmaster would
fail, but we ought to fail a little sooner to protect sysadmins unfamiliar
with Postgres. The chosen fix is to disable root use of pg_ctl in all cases,
just to be confident there are no other holes.
