The ports collection does not support this directly, however it's not
too difficult to set up.
Ports won't allow you to install two different version of PostgreSQL
simultaneously, so the two choices you have are:
1) Install one from the ports and the other manually.
2) Use the jail system to create FreeBSD virtual machines to install
the different versions in.
I like #2 the best, personally, but I've done it both ways. With #1,
you have to ensure they're configured to use different directories
for their data files, and that they listen on different ports. With
#2, you have to change the UID of the pgsql user in each jail so they
don't overwrite each other's shared memory, and enable SYSV SHM for
jails (via sysctl)
