Adding 'crosstab' variants returning refcursor?

Hi all

Before I have a go at hacking it together I wanted to check: Has anyone
explored modifying crosstab to return a refcursor, so you can FETCH the
results w/o having to specify an explicit result type/descriptor?

Consuming the input in another query is more of a pain, but it'd be
infinitely nicer when you just want the results in a client.
