"listen_addresses (string)

     Specifies the TCP/IP address(es) on which the server is to listen
for connections from client applications. The value takes the form of a
comma-separated list of host names and/or numeric IP addresses. The
special entry * corresponds to all available IP interfaces. The entry
0.0.0.0 allows listening for all IPv4 addresses and :: allows listening
for all IPv6 addresses. If the list is empty, the server does not listen
on any IP interface at all, in which case only Unix-domain sockets can
be used to connect to it. The default value is localhost, which allows
only local TCP/IP "loopback" connections to be made. While client
authentication (Chapter 19) allows fine-grained control over who can
access the server, listen_addresses controls which interfaces accept
connection attempts, which can help prevent repeated malicious
connection requests on insecure network interfaces. This parameter can
only be set at server start.
