What is the point in saying this, Michael? What purpose does it serve?

I said "basically uncontroversial", not "uncontroversial". That is a
perfectly accurate characterization of the patch, and if you disagree
than I suggest you re-read the thread. Andres and Heikki were both in
favor of this patch. Heikki and I discussed one particular aspect of
it, and then it trailed off. The only thing that Heikki categorically
stated was that he disliked one narrow aspect of the style of one
thing in one function. I've already said I'm happy to do that.

As things stand, the documentation for amcanunique methods, and the
way they are described internally, is fairly misleading.
