Block creation of partitions with open references to its parent
When a partition is created as part of a trigger processing, it is
possible that the partition which just gets created changes the
properties of the table the executor of the ongoing command relies on,
causing a subsequent crash. This has been found possible when for
example using a BEFORE INSERT which creates a new partition for a
partitioned table being inserted to.
Any attempt to do so is blocked when working on a partition, with
regression tests added for both CREATE TABLE PARTITION OF and ALTER
TABLE ATTACH PARTITION.
