I tried to implement the same type of thing with other RPM packages.
Having multiple versioned RPMs installed is not so easy. Most of the
tools like yum assume you want to upgrade, not install new versions
thus you get lots of problems. (You can designate packages
install-only in yum.conf, but then you have to be sure that everything
works...)

My solution was to create RPMs with the version number embedded in the
name. Thus for 7.4.13 and 8.1.5 I have:

postgres7.4-13-1_fc6.x86_64.rpm
postgres8.1-5-1_fc6.x86_64.rpm

Everything goes into /usr/local/pg7.4 and /usr/local/pg8.1, init
scripts are /etc/init.d/postgres8.1, /etc/init.d/postgres7.4

That combined with some 'alternatives' magic makes things work well
for the hosts at my current job.

spec file(s) available on request...
