Thank you for updating the patch!

I looked at this patch.

vacuumingOptions *vacopts,
        exit(1);
    }

+   if (vacopts->skip_index_cleanup && PQserverVersion(conn) < 120000)

    if (vacopts->skip_locked && PQserverVersion(conn) < 120000)

        PQfinish(conn);

exit(1) is missing after pg_log_error().
