Description:
It is not reseanable that when reorganizing a set of LIST partitions they must be in consecutive order.
When I want to merge partition p0 and p2, it returns an error.
The table is partitioned by LIST, not by RANGE, why only partitions in consecutive order can be merged together?
How to repeat:
mysql> show create table t_add;

mysql> alter table t_add reorganize partition p0,p2 into (partition p0 VALUES IN (1,2,3,4,11,12));
ERROR 1519 (HY000): When reorganizing a set of partitions they must be in consecutive order

Suggested fix:
I suggest merging list partitions not consecutive through "REORGANIZE PARTITION" is allowed in MySQL server.
