Assertion failure when ATTACH partition followed by CREATE PARTITION.

Hi,

Assertion added in commits 6b2c4e59d016 is failing with following test:

CREATE TABLE sales
(
  prod_id           int,
  prod_quantity     int,
  sold_month        date
) PARTITION BY RANGE(sold_month);

CREATE TABLE public.sales_p1 PARTITION OF public.sales
FOR VALUES FROM (MINVALUE) TO ('2019-02-15');

CREATE TABLE sales_p2(like sales including all);
ALTER TABLE sales ATTACH PARTITION sales_p2
FOR VALUES FROM ('2019-02-15') TO ('2019-03-15');

CREATE TABLE fail PARTITION OF public.sales
FOR VALUES FROM ('2019-01-15') TO ('2019-02-15');


Here is the backtrace:

The reported issue has nothing to do with the ATTACH PARTITION stmt this can
also be reproducible with the following CREATE stmts:

CREATE TABLE sales
(
  prod_id           int,
  prod_quantity     int,
  sold_month        date
) PARTITION BY RANGE(sold_month);

CREATE TABLE sales_p1 PARTITION OF sales
FOR VALUES FROM (MINVALUE) TO ('2019-02-15');

CREATE TABLE sales_p2 PARTITION OF sales
FOR VALUES FROM ('2019-02-15') TO ('2019-03-15');

CREATE TABLE fail PARTITION OF sales
FOR VALUES FROM ('2019-01-15') TO ('2019-02-15');

AFAICU, the assert assumption is not correct. In the attached patch, I have
removed that assert and the related comment.  Also, minor adjustments to the
code fetching correct datum.

Indeed, I'd not been paying attention.  Fix looks good, pushed.
