Is it safe to remove postgres after installing 9?

I installed PG9 after following this guide: http://www.davidghedini.com/pg/entry/install_postgresql_9_on_centos

However, as I have not removed postgres the version of pg_dump being picked up is the old version (so some scripts throw a version miss-match error).

I tried creating a /etc/profile.d called pg_dump.sh file and adding this to it:

But still no joy, so changed it to:

And although the script works as it picks up the correct pg_dump version, I get a lot of errors when logging into the server. So I removed it and the errors went (but the original problem remains).

Hence my question, is it ok to remove the original postgres? I think it's a virtual-min-base dependency. I think I heard mentioned that this would be sorted out in a virtualmin update but not sure now. Or maybe someone has a solution to get the correct version of pg_dump to be used?
