Uh.  This is disappointing; the need for some way to unnest or unpack a
multirange was mentioned multiple times in the range_agg thread.  I had
assumed that there was some way to cast the multirange to a range array,
or somehow convert it, but apparently that doesn't work.

If the supporting pieces are mostly there, then I opine we should add
something.
