-For PostgreSQL versions below 14, PostgREST will take into consideration the :ref:`db-use-legacy-gucs` config, which is set to true by default. This means that the interface for accessing these GUCs is `the same as in older versions <https://postgrest.org/en/v8.0/api.html#accessing-request-headers-cookies-and-jwt-claims>`_. You can opt in to use the JSON GUCs mentioned above by setting the ``db-use-legacy-gucs`` to false.
