There's a guide on the Linux Documentation Project here: http://www.tldp.org/HOWTO/Path.html
but it might not be RedHat specific (if that's what you are running).

You probably want to look at /etc/profile - this should be where your path is 
set. It also runs all the files in /etc/profile.d/ (on RedHat)

Perhaps the best method, if you want to keep both versions of PG is to rename 
the "wrong" pg_dump to pg_dump.alt and then you can do (as root)

# cd /usr/bin
# ln -s ../local/pgsql/bin/pg_dump

This will create a link from /usr/bin/pg_dump to /usr/local/pgsql/bin/pg_dump 
which should make it your default.
You can still run the old version as pg_dump.alt - this should help to ensure 
you know which one you are running.
