Sure, and if I had some pointers on what was necessary there I'd take a 
look at it. But I'm not very familiar with plpgsql (let alone what we'd 
need to do this in SQL), so I'd just be fumbling around. As a reminder, 
one of the big issues there seems to be that while plSQL knows what the 
underlying type is, plpgsql has no idea, which seriously limits the use 
of passing it a record.

In the meantime I've got a patch that definitely works for plSQL and 
allows you to handle a record and pass it on to other functions (such as 
json_from_record()). Since that's my original motivation for looking at 
this, I'd like that patch to be considered unless there's a big drawback 
to it that I'm missing. (For 9.6, of course.)
