    Description

      This will fix

      • CHECK constraints
      • UNIQUE constraints WITHOUT OVERLAP
      • UNIQUE constraints that are USING HASH (a.k.a. "long unique")

      Existing cases for WITHOUT OVERLAPS, CHECK are in MDEV-22602 (762bf7a03b6214f091a66ca8683df341112d7d4a) as well as disabled long-uniques (see test case of commit).

      UPDATE must abort if the constraints fail. Long uniques must be rehashed and updated.
