The usage of ``grouped_slice`` without size is deprecated since `= ANY(ARRAY[%s])` is used for PostgreSQL and SQLite is used only for tests. The ``Database.IN_MAX`` is replaced by ``backend.MAX_QUERY_PARAMS`` which is a more accurate limit of the backend. The SQLite limits is indeed SQLITE_MAX_EXPR_DEPTH so we use a empirical value.
