Hm, was this intended for the SELECT man page (presumably in the
"WITH Clause" section), or for section 7.8?

In the SELECT page, I'd be inclined to put it after the para about
"queries need not be ordered" and phrase it more like

  If there are multiple queries in the WITH clause, RECURSIVE can
  be written only once, immediately after WITH.  It applies to all
  queries in the WITH clause (but has no effect on queries that do
  not use either of these features).
