I think this is a good idea, but I felt like you'd added the extra
sentences in not-terribly-well-chosen places.  For instance, your
first addition in trigger.sgml is adding to a para that talks about
triggers for tables, while the next para talks about triggers for
views.  So it seems unclear whether the statement is meant to apply
to view triggers too.

I think it'd work out best to make this a separate para after the
one that defines before/after/instead-of triggers.  How do you
like the attached?
