 port number for
         server and clients. The default is 5432. The port can always
         be changed later on, but if you specify it here then both
         server and clients will have the same default compiled in,
         which can be very convenient.  Usually the only good reason
         to select a non-default value is if you intend to run multiple
         <SPAN
