Now that the psql support for multiple result sets exists, I want to
revive this patch. It's the same as the last posted version, except now
it doesn't require any psql changes or any weird test modifications anymore.

(Old news: This patch allows declaring a cursor WITH RETURN in a
procedure to make the cursor's data be returned as a result of the CALL
invocation. The procedure needs to be declared with the DYNAMIC RESULT
SETS attribute.)
