Description:
CREATE TABLE t (a int)
PARTITION BY RANGE (a)
(PARTITION p10 values less than (10),
 PARTITION p30 values less than (30),
 PARTITION p50 values less than (50),
 PARTITION p70 values less than (70),
 PARTITION p90 values less than (90));

Now insert into t (30); should go into p50 but it rather goes into p30

How to repeat:
See desctiption

Suggested fix:
< changed to <= in while-loop in
get_partition_id_range and get_partition_id_range_endpoint
