I wouldn't necessarily assume the latter ("usually done from
template1"), but these surely seem to be candidates for being fairly
infrequent.
And if they _were_ being touched frequently, would they not trigger
vacuums in the databse that they were being touched in?
In any case, if there are three tables that pg_autovacuum never
touches that _normally_ are pretty quiet, this does not appear to be a
grand disaster.
