This is related to an autovacuum bug and the freeze logic with
template0....and probably a corrupted pg_statistics table in template0....
you should upgrade AND repair the template0 issue (I actually replaced
template0 with a copy from a replicant database)
......But take heed, if you don't 'do' something about it, autovacuum is
actually stopping with tempate 0 and never getting to the rest of your
database (as I found out)
