Should be the same deal as for running 2 versions anyplace else:
give them separate install directories, separate data directories,
and separate port numbers. If you compile from source then you can
make these changes with configure's --prefix and --with-portnum
switches. Not sure you can do it easily with an RPM-based install.
On some systems you may run into kernel limits on SysV shared memory
and/or semaphores when trying to run 2 or more postmasters. See the
documentation about raising kernel limits if so.
