If (auto)vacuum is clever to check that some tables do not need vacuum
there's really no need for that. That brings me to another point, can't the
statistics collector used for that?
For my database I wrote a statistic display program for web-access, and all
the info autovacuum would need is here.

That brings me to another point, is there interest for this
web-statistics-frontend, maybe for /contrib? I found it extremly useful
because it showed up the weak points in my applications.
