Given that the world is going to IPv6 in a few years whether you
like it
or not, that seems pretty darn short-sighted to me.
What would make sense IMHO is to adapt the improved indexing support
in
ip4r to work on the native inet/cidr types.
Can't be done. The native types are too limited to be effectively
indexed
in that way - they cannot represent arbitrary ranges. ip4r started
with me
trying to retrofit decent indexing onto the cidr type and failing
miserably.
I'll likely be rolling out ip6r/ipr sometime in 2008, as users are
beginning to
express an interest. But even then I don't expect it to replace the inet
and cidr types in core, because it isn't compatible with them.
I'd actually support removing inet/cidr from core completely in the
longer
run. Postgresql is extensible, so we really don't need types used only
by niche users in core, once we have pgfoundry and something like
mysqludf.org/CPAN. But that's a longer term thought.
Cheers,
Steve
