One of our customers had problems with the syntax of WITH RECURSIVE. He
suggested that the documentation should be improved, maybe with this
sentence:
"If any of the CTEs is recursive, the recursive keywork must be present
after with", so to make sure that it does not refer to just one of the
named subqueries.
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).

yeah, sounds good to me, thx Tom.
