Well, if we're going to have privs on LISTEN/NOTIFY at all, they should
be on specific message bands, i.e.:
REVOKE LISTEN ON 'cacheupdates' FROM PUBLIC;
GRANT LISTEN ON 'cacheupdates' TO webuser;
GRANT LISTEN ON ALL TO admin;
I can certainly see wanting this, but it'd be a great deal more
sophisticated than what Chris has proposed.
