From c3e9699f212050b0c8bdf3772eeaaffa3c3596cd Mon Sep 17 00:00:00 2001
From: Bruce Momjian <bruce@momjian.us>
Date: Mon, 6 Jan 2003 03:18:27 +0000
Subject: Enable IPv6 connections to the server, and add pg_hba.conf IPv6
 entries if the OS supports it.  Code will still compile on non-IPv6-aware
 machines (feature added by Bruce).
