So ... I want to go ahead and commit Dilip's v4 patch, or something
very like it. Most people were initially supportive. Tom expressed
some opposition, but it sounds like that was mostly to the discussion
going on and on rather than the idea per se. Andres also expressed
some concerns, but I really think the problem he's worried about is
something slightly different and need not block this work. I note also
that the v4 patch is designed in such a way that it does not change
any view definitions, so the compatibility impact of committing it is
basically nil.

Any strenuous objections?
