AFAICT, our code simply hands the string off to a C library function ---
either getaddrinfo() or inet_aton() depending on what your platform has.
If it's not behaving the way you want, it's the fault of one of those
routines.

Just to verify, I changed "127.0.0.1" to "127.1" in my local pg_hba.conf
(this is on HPUX 10.20, which has inet_aton but not getaddrinfo), and
could still connect over localhost TCP ... then changed it to "127.2",
and could not connect. So I don't believe there is anything in the PG
code that is discriminating against addresses written this way.

If you still think the problem is PG's and not your C library's, I
invite you to trace through the code and show where we're going wrong.
But right at the moment I don't believe this is our bug.
