Nalini, your quiet correct that, listen_addresses = * , implies that your server must listen on all network interfaces. Dan does not have an issue with his server listening on all network interfaces. His issue is to restrict the client machines that connect to his server.
Now, he is trying to achieve the above by changing the listen_address configuration parameter and I am saying he must leave it as it is (*) and then modify his pg_hba.conf file (as stated in the previous e-mail).
In case he wants to specify that his server must listen on a specific ip address (say – 201.111.223.222)
Then he must set listen_address = 201.111.223.222 in the postgresql configuration file.
Dan, Do not forget to restart you server after performing any of the above tasks

* in postgresql.conf actually denotes the network interfaces on the machine on which the postgresql server is running. Hi. I think setting Listen_address to *, does In order to apply control over what e.g # TYPE DATABASE USER Host <DBname> DKing Make sure you restart your PostgreSQL Hope this helps. Makgati. From: Hi list,
If you wish to limit access to certain IPs do it in pg_hba.conf.
