Having parsed it what would it do with it? Surely if IP6 isn't
configured in then having an IP6 address in pg_hba.conf is an error.
That's why we commented those lines out in the default pg_hba.conf some
weeks ago.

If Andreas Pflug's patch (with Kurt's caveat) and my patch are applied,
then I really think there won't be any more difficulties in this area.
