I've been able to make a little more progress on multiranges the last
few days, but it reminded me of an open question I've had for awhile:
typmods! I see places in the range code that gesture toward supporting
typmods, but none of the existing range types permit them. For
example:

postgres=# select '5'::numeric(4,2);
 numeric
---------
    5.00
(1 row)

postgres=# select '[1,4)'::numrange(4,2);
ERROR:  type modifier is not allowed for type "numrange"
LINE 1: select '[1,4)'::numrange(4,2);

So I'm wondering how seriously I should take this for multiranges? I
guess if a range type did support typmods, it would just delegate to
the underlying element type for their meaning, and so a multirange
should delegate it too? Is there any historical discussion around
typemods on range types?

Thanks!
