If you are forcing/implying the netmask in the host type, why not just use
it for the netmask? The point of my functions is to extract the different
parts from that.

As far as I understand, that last is the only one we were expecting in
PostgreSQL. So how about this? Let's put back all of the original inet
stuff but call it cidr. Finish your stuff and we'll put it in as the
inet type. Personally I think we just need the latter but I would
rather have both than neither.
I just noticed that this wasn't copied to the list. I hope you don't
mind me copying this response there so that others can add their
opinions too.
