Had the same problem myself. I don't believe there is a way to "short-circuit"
the loop.
See if you can't replace the trigger with a view and a couple of rules. You'll
need one rule to handle the default case and a second to deal with the special
case.
If you need more information, could you please provide the details of your
tables and trigger.
