you can probably set destdir or something in ports to point at /usr/local2 or something, but you will need to be careful that the configs done conflict for listen ip, port and sockets.

the jail solution is quite clean, and allows for a straight up ports install/config.

sorry for the lack of formatting, using tiny keyboard.

Of course you need to add an alias IP for each instance and add that IP on your postgresql.conf "listen_addresses".
