Clarify that ATTACH/DETACH PARTITION can be used to perform partition maintenance with less locking than straight CREATE TABLE/DROP TABLE. This was already stated in some places, but not emphasized. Back-patch to v14 where DETACH PARTITION CONCURRENTLY was added. (We had lower lock levels for ATTACH PARTITION before that, but this wording wouldn't apply.)
