If it's not documented before that time, it probably doesn't exist.

Look at the release notes:

http://www.postgresql.org/docs/8.4/static/release.html

If you have an account on the machine in question, you can install
postgresql there yourself as your own user. That way it won't disrupt
other users of the machine.
