Hmm ... template0 is not supposed to need vacuuming, because it is
frozen ... is it marked with datallowconn=false?

Yes

 select * from pg_database where datname='template0';
  datname  | datdba | encoding | datistemplate | datallowconn | datconnlimit | datlastsysoid | datfrozenxid | dattablespace | datconfig |               datacl               
-----------+--------+----------+---------------+--------------+--------------+---------------+--------------+---------------+-----------+-------------------------------------
 template0 |     10 |        6 | t             | f            |           -1 |         11510 |    201850617 |          1663 |           | {=c/postgres,postgres=CTc/postgres}

So how to fix ?
