+Let's say you have a table called `profiles` in the public schema and you only want users to be able to update their own profile.

+You can create a policy where the `using` clause checks if the user owns the profile being updated. And the `with check` clause ensures that, in the resultant row, users do not change the `user_id` to a value that is not equal to their User ID, maintaining that the modified profile still meets the ownership condition.
