upgrading in RH 8

Are there known issues and how do I get around installing the PostGreSQL
7.4.3 binaries on RH 8?

I tried installing it and it needed dependencies. So I got the
dependencies, which included OpenSSL, but it wouldn't let me update
OpenSSL because the current version is needed for other programs.

It also says postgresql = 7.2.2 is needed by postgresql-server, so it
won't overwrite it.

I tried yum and got an error, "identical dependency errors"
