I have a complete set of working code that tracks buffer usage statistics
as the background writer scans, so that it has an idea what % of the
buffer cache is dirty, how many pages have each of the various usage
counts, that sort of thing. The problem was that the existing BGW
mechanisms were so clumsy and inefficient that giving them more
information didn't make them usefully smarter. I'll revive that code
again if it looks like it may help here.
