Thanks, yes I agree that that is much clearer. However when you say:
When the percentage of dirty shared buffers is high, the background writer writes some of them to the file system...
I haven't seen anything about a minimum percentage before the bgwriter kicks in, is that really the case? How is it configured?
Thanks, Chris.

You make some very good points. Here is an updated patch.
