	Because this is just one part of the process of creating a distributed scheduler. The process for selecting a host for a new instance won't depend on the type of PK used for that instance in a db table.

	The only reason I brought it up was that Sandy pointed out this uniqueness requirement, and we felt it would be a good idea to ask the list if they had any good ideas about alternatives to range partitions. I prefaced my initial post with a disclaimer that I wasn't looking to re-argue things that had already been discussed and agreed to, but I guess most people missed that part. :)
