Re: overlapping ranges

The CREATE TABLE page has this explanation, about FROM and TO in
partitioning declarations:

> When creating a range partition, the lower bound specified with FROM is
an inclusive bound, whereas the upper bound specified with TO is an
exclusive bound. That is, the values specified in the FROM list are valid
values of the corresponding partition key columns for this partition,
whereas those in the TO list are not.
