The "complication" to this is that it is quite likely not simple to do
this using pre-packaged (e.g. - RPM files) Postgres builds.
Anyone that's involved with building Postgres tends to have tooling
handy to help have multiple versions of Postgres around.
I have a script I use for this sort of thing:
<https://github.com/cbbrowne/pginit>
Greg Smith has something analagous, though more sophisticated:
<https://github.com/gregs1104/peg>
It amounts to:
1. Installing both versions of software;
2. Possibly using scripts to help manage where the results get
installed.
If you're accustomed to entrusting installation totally to RPM-based
installations of Postgres, you're headed into new territory to have to
choose and configure where the installations are done. But it's really
no big deal - it's not unusual for me to install several different
instances of Postgres in the course of an hour, refreshing some
instances I use to test Slony-I.
