I think maybe my actual argument isn't coming through. What I am arguing
for is not shipping XY without Z. That is all. (and no, I don't think we
should hold up 8.4).
In short. Let's do the feature but don't ship half of it. Ship the whole
thing. If that means it doesn't get into 8.4, then it doesn't get into
8.4.

You don't have to convince me. I agree with you.

O.k. I was with you until here. Log shipping ala pg_standby works fine
now sans read-only slave. No, it isn't out of the box which I can see an
argument for but it is certainly trustworthy. Or do you mean the
synchronous part?
