Helper class for encapsulating new/altered partitions during ADD(HASH/KEY)/COALESCE/REORGANIZE PARTITION.
Here as many partition slots as in new table would be created, it's OK for ADD/COALESCE PARTITION, however more partition slots would probably be created for REORGANIZE PARTITION. Considering that it's easy to get table in this way, it's still OK.
