With the patch I submitted yesterday it would just work out of the box
and no error message. ISTM the default setting should do just that.

Have a look at the patch:
http://archives.postgresql.org/pgsql-patches/2003-09/msg00010.php

The only "special" thing it does is in deciding if a connection matches
the rule. Otherwise it is treated exactly the same as any other network
connection.

Ignoring entries is probably storing up trouble for yourself in the
future. Say I mistype "192.168:1.1" on an IP4 only machine and it is
silently ignored?

Commenting out / uncommenting entries is problematic. The only sane time
would be to do it at initdb time, ISTM. But what if IP6 is turned on
after you run initdb? BOOM no work. With my patch you would keep working
happily :-)

I'm done arguing about this - I'll leave it up to the committers to
decide what they want to do and move on to something else.
