Well, the point was that if the partitioning arrangement guarantees to
put distinct ranges of the key into distinct tables, then a separate
unique constraint on each table would suffice to guarantee global

You can set up such a thing today, but it's a manual jury-rigged affair.
An automatic partitioning system would be a lot nicer.
