Surabhi - can I suggest you just stick to the RPMs? If you're not sure
how to remove RPMs then you'll want to move slowly until you have more
experience of Linux system administration.

You almost certainly have some sort of graphical package-manager if
you're running a recent redhat/suse and that will give you the most
recent packaged version for your distribution.

If you want something not provided by your distribution though...

1. pg_dump all your existing databases (just to be safe) and check that
you know how to restore them and that they contain data.
2. Go to http://www.postgresql.org/ and look for "Latest Releases"
    Click the "binary" link next to "8.0.6"
3. Click linux, rpms, and work down to your version of redhat/fedora.
4. You'll want these:
       postgresql-8.0.6-1PGDG.i686.rpm
       postgresql-server-8.0.6-1PGDG.i686.rpm
       postgresql-docs-8.0.6-1PGDG.i686.rpm
       postgresql-libs-8.0.6-1PGDG.i686.rpm
     and possibly one or more of:
       postgresql-contrib-8.0.6-1PGDG.i686.rpm
       postgresql-jdbc-8.0.6-1PGDG.i686.rpm
       postgresql-pl-8.0.6-1PGDG.i686.rpm
    Download them all to a suitable directory and then
5. rpm -Uvh postgresql*rpm
    This should upgrade your existing installation and then you can
restore your databases.
6. Get a good book on linux administration - plenty out there and you
can check reviews online. Set aside a few days to spend making sure you
understand how to manage RPMs, backups, the root user, admin tools like
ps/top/lsof etc.
