In this exercise, we'll go thru installing PostgreSQL 9.0 on a Cent OS 5.5 32-bit box. This I'm testing on a GoGrid Cloud server so I can do parallel benchmarks between my windows GoGrid
and Linux GoGrid server.
For the rest of this article, we'll go over configuring your yum to use the PostgreSQL PGDG Yum repository managed by Devrim Gunduz, which has the latest and greatest of
9.0 as well as the 9.1 latest development release. We'll also demonstrate how to have two instances of PostgreSQL running so you can experiment with the new features of
PostgreSQL 9.1 while reminiscing about the soon to be old-hat features of PostgreSQL 9.0.
