No, because the reltuples counts are correct. I think what we're
looking at there is the stats collector dropping a packet that
told it about vacuum activity.
I'm surprised that we saw such a failure so quickly. I'd always
figured that the collector mechanism, while it's designed to be
unreliable, is only a little bit unreliable. Maybe it's more
than a little bit.
