That should only be a problem if you want to use IPv6.

Can you connect to the server via network? If yes, then I wouldn't worry
about the message.

You can avoid the message by specifying an explicit IP address or
host name for the IPv4 connection in listen_addresses instead of "*".

Thanks Laurence for Reply.
I can actually connect to server using network. I am just trying to
avoid this warning.  Your solution for listen_address will work but I
want to keep it as "*" . Somehow it doesn't complain on any other *nix
Operation Systems.


Thanks & Regards,
Vikram

Probably IPv6 is set up correctly on the machines where you don't get an error.

You can unconfigure IPv6 on the AIX, then PostgreSQL won't try to
listen on IPv6 ports.

Ask the system administrators of the machine for help.
