hi.
When using ALTER TABLE ... MERGE PARTITIONS, some of the new
partition's properties will
not be inherited from to be merged partitions; instead, they will be directly
copied from the root partitioned table.
so we need to test this behavior.
The attached test file is for test table properties:
(COMMENTS, COMPRESSION, DEFAULTS, GENERATED, STATISTICS, STORAGE).
STATISTICS: to be merged partition's STATISTICS will be dropped.
COMMENTS: to be merged partition's COMMENTS will be dropped.
