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.

Though its not harmful but its misleading 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 "*".
