We have just finished porting the old KAME IPv6 patch over to
postgresql version 7.3, but yea... this patch adds full IPv6 support to postgres. I've tested it out on 7.2.3 and has been running perfectly stable. CREDITS: The KAME Project (Initial patch) Nigel Kukard <nkukard@lbsd.net> Johan Jordaan <johanj@lando.co.za>
