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.
