Nope, those are not autovaccum related logs , they are related to queries
only.

You have log_autovacuum_min_duration = 0 below.

On the chance that this setting is being overridden somewhere what does
the below show when run as a superuser?:

select * from pg_settings where name= 'log_min_duration_statement';
