The documentation said that the bounds of new partitions should not overlap and that their combined bounds should equal the bounds of the split partition. That is misleading when a new DEFAULT partition is specified, because the explicit partitions may cover only part of the split partition while the DEFAULT partition covers the rest. Clarify that new non-DEFAULT partition bounds must not overlap with other new or existing partitions and must be contained within the bounds of the split partition. Also state that the combined bounds must exactly match the split partition only when no new DEFAULT partition is specified. While here, improve nearby wording about hash-partitioned target tables and splitting a DEFAULT partition with the same partition name.
