This works in 9.5:

CREATE FUNCTION test_event_trigger_for_create()
        RETURNS event_trigger LANGUAGE plpgsql AS $$
DECLARE
    obj record;
BEGIN
    FOR obj IN SELECT * FROM pg_event_trigger_ddl_commands()
    LOOP
        RAISE NOTICE '% created object: %',
                     tg_tag,
                     obj.object_identity;
    END LOOP;
END
$$;
CREATE EVENT TRIGGER test_event_trigger_for_create
   ON ddl_command_end
   EXECUTE PROCEDURE test_event_trigger_for_create();


Demo:

test=*# create table foo (i int);
NOTICE:  CREATE TABLE created object: public.foo
CREATE TABLE
test=*#
