It depends on your reason for partitioning -- if you mean to drop a partition in the future (to roll off the 1999 data or whatever) then the ID range is potentially a valid approach, as long as ID is serial. If you just want to put chunks on different disk volumes, you could use the type or even a hash partitioning scheme. It's down to what you're trying to accomplish, and what is good for one partition key is probably bad or neutral for the other.
