Robert Haas 3ec76ff1f2 Don't explicitly mark range partitioning columns NOT NULL. This seemed like a good idea originally because there's no way to mark a range partition as accepting NULL, but that now seems more like a current limitation than something we want to lock down for all time. For example, there's a proposal to add the notion of a default partition which accepts all rows not otherwise routed, which directly conflicts with the idea that a range-partitioned table should never allow nulls anywhere. So let's change this while we still can, by putting the NOT NULL test into the partition constraint instead of changing the column properties.
