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. regards, tom lane
