Double errmsg(). (Maybe an Assert somewhere should help catch this?)

I would like to see some tests that the unique constraints are actually
enforced. That is, insert some duplicate values and see it fail. Throw
some null values in, to check PK behavior as well. It should be
trivial, but seems kind of useful.
Other than that, this looks pretty good to me. A logical extension of
the previous partitioned index patch.
