If the system has IPv6 enabled, it's not possible for there to be no ipv6 address.

The problem here is that the system cannot *parse* the address ::1. This should not have anything to do with which addresses exist or could exist. -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
[HACKERS] non-ipv6 vs hostnames
Accidentally specifying an IPv6 address in pg_hba.conf on a system that doesn't have ipv6 support gives the following error: LOG: specifying both host name and CIDR mask is invalid: ::1/128 Which is obviously wrong, because I didn't do that. Do we need to detect and special-case ipv6 addresses in this case? FWIW, the line was simply: hostreplication all ::1/128 trust -- Magnus Hagander Me: http://www.hagander.net/ Work: http://www.redpill-linpro.com/ -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers

Do we need to detect and special-case ipv6 addresses in this case? Doesn't really seem worth going out of our way for that. Systems with no IPv6 support are a dying breed, and will be more so by the time 9.2 gets deployed. regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
