I'm not sure if I understand what your problem is. If a query
does not return any rows (pg_numrows() < 1) then that is not
really a "failure". If the SQL was incorrect then I would
suggest printing it to the browser (echo $query) and pasting it
in a query program like psql or winsql to determine which line
of code was incorrect.
