The PostgreSQL 8.4 is coming from the default latest CentOS 6.3 updates repository which makes it an easy install and upgrade later (yum install postgresql-server). I'll try installing/upgrading my test setup using http://yum.postgresql.org repository. I'm also going to need to find out what migrating to a newer version will affect with the current production data.

It sounds like you're trying to keep them on 8.4. Why not move them to some newer release branch where you can make use of streaming replication? Aside from the benefits of that, 8.4 will be out of support next year, so setting up new servers with that release series seems pretty short-sighted.
I realize that dealing with a version upgrade might not be their highest priority right now, but they're going to have to deal with it before too long, and doing so now would put them in position to have a far better replication solution than what you're describing.
