If we went with that, and had:
CREATE TABLE orders (order_id serial, order_date date, item text)
PARTITION BY RANGE ON (order_date) INCREMENT BY (INTERVAL '1 month')
START WITH '2015-01-01';
Where would the following go?
INSERT INTO orders (order_date, item) VALUES ('2014-11-12', 'Old item');
Would there automatically be an "others" partition? Or would it produce an
error and act like a constraint?
