Hi,

I observed, when creating foreign table with range partition, data is not
inserting into specified partition range. below are steps to reproduce.

CREATE EXTENSION postgres_fdw;
CREATE SERVER pwj_server FOREIGN DATA WRAPPER postgres_fdw OPTIONS (dbname
'postgres', port '5432',use_remote_estimate 'true');
CREATE USER MAPPING FOR PUBLIC SERVER pwj_server;

CREATE TABLE test_range (a int) PARTITION BY RANGE(a);

CREATE TABLE test_range_p1 (a int);
CREATE FOREIGN TABLE ft_test_range_p1 PARTITION OF test_range FOR VALUES
START (1) END (10) SERVER pwj_server OPTIONS (TABLE_NAME 'test_range_p1');

CREATE TABLE test_range_p2 (a int);
CREATE FOREIGN TABLE ft_test_range_p2 PARTITION OF test_range FOR VALUES
START (20) END (30) SERVER pwj_server OPTIONS (TABLE_NAME 'test_range_p2');

CREATE TABLE test_range_p3 (a int);
CREATE FOREIGN TABLE ft_test_range_p3 PARTITION OF test_range FOR VALUES
START (10) END (20) SERVER pwj_server OPTIONS (TABLE_NAME 'test_range_p3');

postgres=# INSERT INTO test_range (a) values (5),(25),(15);
INSERT 0 3

postgres=# select tableoid::regclass, * from test_range;
     tableoid     | a
------------------+----
 ft_test_range_p1 |  5
 ft_test_range_p2 | 15
 ft_test_range_p3 | 25
(3 rows)

--Here ft_test_range_p2 is created for range 20-30 having value 15.
