Per SQL spec (in particular, the grammar in SQL:2008 7.13) we should allow
parentheses around the <query expression body> that follows a WITH clause, eg with cte(foo) as ( values(0) ) ((select foo from cte)); This seems to be just an oversight/thinko in gram.y. Noted while experimenting with bug #4902.
