I put it back, mostly because I don't really care and it's easily
removed if people don't want it. (I used a different wording though,
not necessarily final.)

I also realized that if you rename a trigger and the target name is
already occupied, we'd better throw a nicer error message than failure
by violation of a unique constraint; so I moved the check for the name
to within renametrig_internal(). Added a test for this.

Also added a test to ensure that nothing happens with statement
triggers. This doesn't need any new code, because those triggers don't
have tgparentid set.
