QNX 4 does not support UNIX domain sockets. Clients must use TCP/IP
-sockets. Therefore you either have to set "tcpip_socket = true" in
-your postgresql.conf or to start postmaster with the -i option.

+"listen_addresses" in an environment using native QNX networking.
Otherwise the postmaster might not use the IP-Address you think it does :-)
