The only issue is storing a timezone-less timestamp into a field that
is timestamp with timezone. Every other combination is easy to handle.
If you're doing this, isn't it an indication that your field is the
wrong type? It's just plain ambiguous no matter which way you put it.
Assuming UTC would be almost as valid.
We don't promote integers to other types of numbers, so maybe this
shouldn't be allowed either.

Except that means your program will work all the time except for one or
two hours per year where it breaks. Chances are your testing is not
going to trip it...
