Here's v8 of this patch. I have fixed the problems pointed out by Jaime
and Erik, as well as incorporated Zhihong, Erik and Justin's
documentation fixes (typos and otherwise).

Not yet included: a fix for Peter's suggestion to raise a good error
when both tables use the same name.

Individual changes can also be seen in
