Ok, looked at these more closely.

The one place that very slightly bothers me is the ::1 line in
pg_hba.conf. The fact that it comes last in the default config is its
saving grace - it won't ever be reached by a passing connection. I think
at least, though, we should put a warning comment line in front of it,
to the effect that if they see 'LOG: invalid IP address "::1"' in the
log or a connection message like 'FATAL: missing or erroneous
pg_hba.conf file' they probably need to comment the line out.

I agree that most of the others don't matter (most are there just for
case branches for AF_INET6).

Apart from pg_hba.conf.sample (if you agree with the above), it looks
like just port/getaddrinfo.c will need tweaking.
