Yeah, I'd be very surprised if many need it, and those who do can uncomment it. I think commenting it out is the right thing (tm).

Say what? This is with a completely default pg_hba.conf file... looking in the postmaster log as suggested:
LOG: could not interpret IP address "::1" in config file: Unknown server error LOG: invalid entry in pg_hba.conf file at line 55, token "::1" FATAL: missing or erroneous pg_hba.conf file HINT: See postmaster log for details.
In short, it will not do to put IPv6 addresses into pg_hba.conf by default on machines where IPv6 support is not present.
While we could gin up some mechanism to adjust the installed copy of pg_hba.conf.sample depending on whether we detected IPv6 support, I am inclined to simply remove or comment out the IPv6-specific entry in the sample file. I doubt that many people actually need it, and the ones who do can just adjust the sample file.
Comments?
