I like that idea. It's far simpler than the kind of stuff I was
thinking about, and probably just as effective. Even if it introduces
some unforeseen problem (which seems unlikely), we can still rely on
pgstat_report_vacuum() to set things straight before too long.

Are you planning on writing a patch for this? I'd be very interested
in seeing this through. Could definitely review it.
