What's the other one?

The main problem I've got with this patch is that there's no place to
shoehorn the information into the textual EXPLAIN format without
breaking a lot of expectations (and hence code --- it's insane to
imagine that any significant amount of client-side code has been
rewritten to make use of xml/json output yet). It would be nice to know
what other requests are likely to be coming down the pike before we
decide exactly how we're going to break things.
