+Functions that return ``record`` or ``SETOF record`` are supported:
+
+.. code-block:: postgres
+
+  create function projects_setof_record() returns setof record as $$
+    select * from projects;
+  $$ language sql;
+
+.. tabs::

+
+    GET /rpc/projects_setof_record HTTP/1.1
+
+  .. code-tab:: bash Curl

+    curl "http://localhost:3000/rpc/projects_setof_record"
+
+.. code-block:: json

+  [{"id":1,"name":"Windows 7","client_id":1},
+   {"id":2,"name":"Windows 10","client_id":1},
+   {"id":3,"name":"IOS","client_id":2}]
+
+However note that they will fail when trying to use :ref:`v_filter` and :ref:`h_filter` on them.
+
+So while they can be used for quick tests, it's recommended to always choose a strict return type for the function.
