Re: CIDR in pg_hba.conf

I would far rather have standard CIDR notation - inventing a new one for Pg
doesn't make sense to me.

I do not at all understand the objection to a variable number of fields. In
fact, we already have them (there's an optional authentication_option on the
end).

If you don't like this scheme, you can avoid use of CIDR notation (or
hostnames) and the pg_hba.conf will work exactly as before.
