I agree with you.



also v13-0003-Remove-dependence-on-integer-wrapping-for-jsonb.patch
in setPathArray we change to can

        if (idx == PG_INT32_MIN || -idx > nelems)
        {
            /*
             * If asked to keep elements position consistent, it's not allowed
             * to prepend the array.
             */
            if (op_type & JB_PATH_CONSISTENT_POSITION)
                ereport(ERROR,
                        (errcode(ERRCODE_INVALID_PARAMETER_VALUE),
                         errmsg("path element at position %d is out of
range: %d",
                                level + 1, idx)));
            idx = PG_INT32_MIN;
        }
