AFAICS, Alex is quite far out in left field to believe that this is a
standard notation. The fact that some BSD platforms have accepted it
does not make it standard, especially not when Vixie's research shows
that there is no RFC to legitimize it. (Personally I never heard of
it before either, not that that proves much...)

I can't get excited about replacing or second-guessing the platform's
getaddrinfo() or inet_aton() implementation. If you don't like how
those library routines behave, forward your bug report appropriately
--- but it's not Postgres' problem.
