Catalog check the identity of partition using the name of partition instead
of location. In above case, the name of partition is
``n_regionkey=1,n_nationkey=2``. If you didn't execute ``alter table drop
partition statement``, the partition of (n_regionkey=1,n_nationkey=2) exists on
catalog. Could you execute ``alter table add partition statement`` after
executing ``alter table drop partition statement``?
> Implement logical plan part and DDL executor for alter partition.
