This is not actually a leak since the application will terminate immediately if
a restrict key cannot be generated.  If you inspect the callsites you will see
this pattern:

    if (!restrict_key)
        restrict_key = generate_restrict_key();
    if (!restrict_key)
        pg_fatal("could not generate restrict key");
