[cobalt-users] Wrecked PostgreSQL installation

Can anyone help me with the following problem? I leased a Cobalt RAQ3 dedicated server in the US and since I needed some software that didn't come pre-installed, I installed samba server, Apache J-serv, Sun's JDK 1.2 and... since I didn't know that Cobalt uses the PostgreSQL database I just thought that it would be wise to remove all the "old" PostgreSQL RPMs and install the new ones. Problem is that Cobalt does PostgreSQL and now I cannot administer the machine via the web. Can anyone tell me where can I get the orginal PostgreSQL RPMs that come with Cobalt (6.5.2-2C I believe). I still have the cobalt databases so no data has been lost but I don't mind if I loose it, since I had only two sites configured. If the RPMs are not available, is it safe to remove any PostgreSQL package and install a completely new version and just recreate by hand the databases? Has anyone done anything like this? (Note : I don't have physical access to the machine,only a telnet shell access as root)
