It does happen, and not infrequently. Just not enough pages to normally
cause significant bloat. The most likely place where it happens is very
small tables that all connections hit with a high frequency. Starting to
issue high volume log spew for a nonexistant problem isn't helping.
If you're super convinced this is urgent then add it as a *single*
datapoint inside the existing messages. But I think there's loads of
stuff in vacuum logging that are more important this.
