D6 runs fine on CentOS 6. There may be a few stray contrib modules out there that don't like it, but I haven't come across any. Two of my biggest clients are on CentOS 6 and never have a problem.
As far as Postgresql, I really can't say. All my clients run on MySQL.

In your position I would be most reluctant to change software versions. My recommendation is that, if possible, you to recreate your broken CentOS 5 system in a VM and run your site on that. Changing everything at once with, I suppose, no planning isn't ideal.
fwiw I have D7+Postgres running in a (virtual) CentOS 6 system. There's negligible load (and never will be much), but everything functions okay.
I've not tried D6 on it.
