Well, if we're gonna do it we should do it for v16, rather than
change the data structure twice.  It wouldn't be hard exactly:

    /*
     * Clear fields that should not be set in a subquery RTE.  Note that we
     * leave the relid, rellockmode, and perminfoindex fields set, so that the
     * view relation can be appropriately locked before execution and its
     * permissions checked.
     */
-   rte->relkind = 0;
    rte->tablesample = NULL;
    rte->inh = false;            /* must not be set for a subquery */

plus adjustment of that comment and probably also the comment
for struct RangeTblEntry.
