Agreed. I spent close to a week trying different benchmarks and
configurations and simple test cases on a test server and my laptop, and
couldn't demonstrate bgwriter making a positive impact in any
configuration I tried. The theory behind the patch is sound, but it
looks like a lot more testing and analysis is needed.

It was waiting on the "vacuum oldestxmin" patch, which didn't make it to
8.3. I don't care for the patch myself, but it was submitted well before
feature freeze and deserves a review. It looks good to me at first glance.
