apt-get upgrade or .tgz

["Andrew P. Kaplan" <noc@cshore.com>]

I have an old version of Postfix running on my Debian box. I don't remember
if I used apt-get or installed from a .tgz file. If I use apt-get install I
am concerned I could end up with two version of Postfix. What's the best way
to upgrade.
