Right. I guess you misunderstood me: I was arguing for rejecting double
occurrences of the same unit name, but not occurrences of different unit
names that we happen to map into the same interval field internally.
IOW the behavior ought to be predictable without knowing which unit
names map to the same field.

I forget --- are the tmask bits used in stored typmod values for
intervals? It'd probably be best not to change the meanings of typmod
bits, since those are visible to client code if it wants to look.

Hmmm ... if you check the cvs history for those tests you might find
