No, I don't have any ideas --- I was just agreeing that it'd be a nice
thing if we could do it.
I am planning to add a "hook" field into the fmgr interface to allow
dealing with function results that can't be returned as a single Datum
(see previous discussions on hackers list). But I'm not going to try
to write any code that makes use of that hook, at least not for 7.0.
