I think you want your if blocks to be more like:
if tg_op = ''INSERT''
if cat.category is null
(raise exception)
else
(do insert stuff)
end if
end if
if tg_op = ''DELETE''
(do delete stuff)
end if

I think you're currently going to get into the
insert stuff on both inserts where it isn't
null and deletes (since in both cases the
and will be false).
