That certainly makes sense for user_2 that owns the reference table and is blocked by not having usage on the reference table’s schema. But, user_1 owns both schemas and has usage on both but no longer owns the reference table in one schema. Why is user_1’s insert on the referencing table failing? Is the validation of the FK no longer done as user_1?
