Log message:
    Significant improvements to the documentation for the new cost-based
    vacuum delay feature, including updating the docs for Tom's recent
    improvements. There is still more work to be done here: for example,
    adding some more information on the practical use of cost-based
    vacuum delay to the "maintenance" section would probably be a good
    idea.
