Hmm ... no, it does work, because we'll stop at the first trigger
with tgparentid = 0, so unrelated triggers further up the partition stack
don't matter.  But this definitely requires commentary.  (And I'm
not too happy with burying such a complicated thing inside a conditional
inside a printf, either.)  Will see about cleaning it up.
