We use it in both on separate boxes as well as local. As long as your
machine is handling the connection processing of the pooler fine, I
wouldn't worry about it. There are some specific high end off machine
things you can do (point at different databases on different machines
from a single pooler) that is cool but for just a Drupal website it is
probably not required.
