Well, that's why template0 is getting vacuumed. At some point
someone must have set it to allow connections; otherwise you would
have zero for commits, rollbacks, and all those block and tuple
counts. I'm not sure whether you can get past that now by allowing
connctions, running VACUUM FREEZE ANALYZE on it, and disabling
connections again, but it might be wroth a try.
