Help for postgresql binary installation v.8.0.3

Hi there,

I am installing postgresql v. 8.0.3 binary on a redhat linux rhel 3.0.
What rpms are needed and in what order for installation since I see a
slew of rpms below. It be great if there is documentation for binary
installation for postgresql v.8+ as well. If so, let me know.
