You could maybe make the same-port trick work if you chroot one or both postmasters, or relocate the socket directory to someplace besides /tmp, but either of those approaches will make life difficult for clients trying to make local non-TCP connections. On the whole, separate port number is the path of least resistance in almost all cases. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 5: don't forget to increase your free space map settings
