We also should not perform this conversion if we have

Another case when conversion should not be performed is when
we have ON DELETE trigger on table so user may notice that
we cheat here. Note that it is ok to do such conversion for
tables which have ON UPDATE but have no ON DELETE triggers,
we just should not expose this fact to users by invoking
