It is in my opinion, it is the most modern and maintainable of the
methods for obtaining network interface address information. Various
unixes have added support for getifaddr() over the years, and (again my
opinion) would probably continue to do so.

I do know that using SIOCGIFCONF on AIX comes with strange wrinkles and
variable length data structures etc... getifaddrs() on AIX is a far more
maintainable interface.

That said, I'll adjust the patch as you feel is best for the long term
inclusion in the postgresql source.
