I'm more than a bit skeptical of that claim. Under what circumstances (other than a really awful hash function, perhaps) would it make sense to not use equi-sized hash partitions? If you can predict that more stuff is going to go into one partition than another, then you need to fix your hash function, not invent more complication for the core partitioning logic. regards, tom lane
