As I've said in a private discussion, the way the questions were
asked was not clear. I think that the decision should be based on
the type of operation, e.g.
 * interval -> interval
 * other -> interval
 * interval -> number (IEEE 754 format or not)
 * interval -> text
 * reduction operations

That's at least 6 cases (including the 2 cases for interval -> number).
