Hi Bertrand, It would be helpful to me if the reasons why we're splitting out relfilenodestats could be more clearly spelled out. I see Andres's comment in the thread to which you linked, but it's pretty vague about why we should do this ("it's not nice") and whether we should do this ("I wonder if this is an argument for") and maybe that's all fine if Andres is going to be the one to review and commit this, but even if then it would be nice if the rest of us could follow along from home, and right now I can't.
The commit message is often a good place to spell this kind of thing out, because then it's included with every version of the patch you post, and may be of some use to the eventual committer in writing their commit message. The body of the email where you post the patch set can be fine, too. ...Robert
