Problems with Pg::doQuery-- Fixed

Ok, seems if I use \@ary instead of defining it as \@clients it seems to
work..

But since I am on the subject, I have my database on a remote location
from my Webserver, so of course I always worry about response time..
Comparing the ::doQuery vs exec statements, (And the associated
->ntuples, ->fnames, and looping ->getvalue's, etc that are required)
How does response times compare?
Any comments on which is the more affective procedure?
