I looked at 0001. It seemed to me that it wasn't that useful to add a
context unless we did something about actually freeing it; otherwise
we're just increasing the amount of memory leaked after a function
redefinition. However, it proved pretty easy to shoehorn in a refcounting
mechanism like plpgsql has, so I did that and pushed it.
Off to look at 0002 next.
