I thought of a better way: we can bypass the need to use a non-inlined
SQL function by declaring internal-language aliases for the
auxiliary-lock functions that are falsely marked parallel-safe.
It's a little bit ugly (see [1]) but I think it beats not running
this test under debug_discard_caches at all.
