We can't: the only possible fix is to make inet-to-cidr not be a binary
compatible conversion but instead have an actual conversion function.
IMO the other direction should probably not be straight binary
compatible either; instead it ought to flip the bit that says "I'm a
CIDR value".
So fixing this requires a couple of new functions and some pg_cast
changes. Since we already forced initdb for beta4, there is a window of
opportunity to do that without any extra pain for beta testers, but the
fix would have to happen *now*.

Personally I'm inclined to leave it for 8.1. The inet/cidr code is
really designed around the assumption that these datatypes are
interchangeable, and I suspect that enforcing a stronger distinction
will actually take much more wide-ranging changes than just this.
Do all of the functions on inet/cidr take care to deliver a value that
is both correctly marked and declared as the correct type? I doubt it.
It needs some thought not just a band-aid ...
