And be sure to check no table has unexpectedly individual autovacuum
turned off :

select pg_class.oid::regclass,relkind, opts.* from pg_class JOIN LATERAL
pg_options_to_table(reloptions) opts ON (true) where relkind not in
('i','v','S') AND option_name ~* '.*autovacuum_enabled' AND
option_value='false'
