Hi Tom,
Thanks for the advice. Autovacuum is disabled in the environment and I cannot take a call on enabling it back. I can only run manual vacuum on the database as the dev team fears autoanalyze changing the query performance.
Do you still think we don't need to take any actions.
Thanks,
Rijo Roy

Thought of setting it to true and perform a vacuum freeze on the same. Before doing that, I wanted to check whether I should be worrying for something here or can I just go ahead with my plan.
I would leave well enough alone. Unless you've changed the default
values of autovacuum parameters, that behavior is perfectly normal
and not worrisome. autovacuum should kick in and do something
about it at 200 million xacts (autovacuum_freeze_max_age).
