Re-reading the thread quickly, it seemed like there was considerable
pushback about the cost of collecting the stats, and worries about whether
it wouldn't just be log spam.  But I think the opposite of the latter
concern is also valid, namely that people who could benefit from the
warning are not going to see it because they don't peruse the postmaster
log carefully/at all.  That's a generic problem for warning messages
emitted by background tasks, which we ought to think about how to fix.
In the meantime though it seems like this patch is far more likely to be
annoying than helpful.

I'd vote for rejecting and annotating the TODO item with a link to
this thread.  And maybe taking off the "easy" notation.  I think the
TODO item is reflecting a real usability issue, but solving it usefully
is quite a bit harder than it looks.
