Greg had worried about being able to turn this behavior off, so we'd still need at least a bool, and we might as well expose the fraction instead. I agree with removing the non-LRU part of the bgwriter's write logic though

If you accept that being able to turn LDC off is important, people who aren't turning it on may still want the existing bgwriter_all_* settings so they can keep running things the way they are now. It's certainly reasonable to skip that code path when doing things the LDC way.

Well, if you don't want anything to change, don't upgrade.
