OK, there are more problems.  If you apply the following patch to the
regression tests you will crash the backend in a number of places.  I
also added some null inserts in places that it didn't crash (the date
and time functions are pretty clean) but it will, of course, change
the expected output.

I won't send this to patches since it crashes the backend.  I'll let others
fix the tests for the types that they fix.
