-------------------------------------+-------------------------------------
MariaDB 10.2+ support check constraints (see
[https://mariadb.com/kb/en/library/constraint/#check-constraints check-
constraints]), we should support them because we officially support this
database. I created [https://github.com/django/django/pull/11513 PR] to
fix feature flags but it requires more work e.g. with introspection.
