+Statistics Collector Fun on AIX
+--------------------------------
+
+When implementing PostgreSQL version 8.1 on AIX 5.3, we periodically
+ran into problems where the statistics collector would "mysteriously"
+not come up successfully.
+
+This appears to be the result of unexpected behaviour in the IPv6
+implementation. It looks like PostgreSQL and IPv6 do not play very
+well together at this time on AIX.
+
+Any of the following actions "fix" the problem.
+
+1. Delete the localhost ipv6 address
+
+(as root)
+# ifconfig lo0 inet6 ::1/0 delete
+
+2. Remove IPv6 from net services. The file /etc/netsvc.conf, on AIX,
+is roughly equivalent to /etc/nsswitch.conf on Solaris/Linux.
+
+The default, on AIX, is thus:
+
+ hosts=local,bind
+
+Replace this with:
+
+ hosts=local4,bind4
+
+to deactivate searching for IPv6 addresses.
