Yes, the instance already running is live in that users are indirectly querying/writing to it. I just need to launch a 2nd instance.

I used the graphical installer to install PG 9.4 on this system. Also,
my OS is RHEL 6.5. Thanks for any help!
Hmm, not sure you can mix this with an RPM install. I thought I remember that the graphical installer could deal with multiple instances, but I do not use it personally so that is just a guess. Maybe someone with more experience with it could offer a suggestion.
One more question?:
Is the 9.4 instance you have running a live production database?
If not it might be easier to start over using a different method assuming that you cannot get the graphical method to install side by side instances.

Is this accurate from what you perceive? It also says to have
separate
init.d scripts (startup). Thanks

Well if you really have your heart set on this I would take look at
this:
http://yum.postgresql.org/howtoyum.php
Though the above would depend on how you installed your current
version of Postgres 9.4.
So where did you install it from?

init the cluster on the file system you want using -D,
assuming the
VM can access that file system.
FYI, best practices is not to run on NFS, so do not be
surprised if
things break.
Has anyone done this and is it possible with no issues?
Or is it better to run different versions of PG on same
server?
No, you just need to make sure the Postgres clusters are
listening
on different ports. That means going into postgresql.conf
in the
cluster and changing the port variable.
Please advise. Thanks
