[GENERAL] Listening on more than one port?

[Michael Nolan]

I need to be able to have postmaster (8.1.2) listen on more than one port, eg, 5432 and some other port, such as 5431.

There does not appear to be a way to configure that. You can configure multiple IP addresses, but not multiple ports.

If I set up a TCP port redirector like rinetd, to forward packets from port 5431 to port 5432 it appears to be forwarding packets to the right port with a simple telnet session (based on errors in the log file) but psql still says there is no postmaster listening on port 5431.

Is there a simple way to do this that I'm overlooking?
