I don't think so ...

I think that warning is what to pay attention to, and not the fact
that your script falls over when pg_numrows then chooses to return 0.

I don't know enough about PHP to know what you did wrong, but apparently
$res does not contain the kind of object pg_numrows expects.  I think
it's a PHP problem, not an SQL issue at all.
