Do managed postgres databases run the autovacuum demon?

As described here -

I didn’t see any mention in the DigitalOcean docs, so I assume not, but wanted to make sure - I’m new to pg and not sure what is standard.

I reached out to support some time back with that very question

Currently, in our managed Postgres database we have autovacuum enabled and below are some of the values we have set for the parameters that affect autovacuum 

autovacuum_analyze_scale_factor | 0.1 

autovacuum_analyze_threshold | 50

autovacuum_freeze_max_age | 1000000000 

autovacuum_max_workers | 3 

autovacuum_naptime | 60 s

autovacuum_vacuum_cost_delay | 20 ms

autovacuum_vacuum_cost_limit | -1

autovacuum_vacuum_scale_factor | 0.2

autovacuum_vacuum_threshold | 50

maintenance_work_mem | 154624 kB

vacuum_cost_limit | 200

vacuum_freeze_min_age | 50000000

I think the answer is yes. Anyways it would be nice to have confirmation from official side.

According to this documentation page and as pistle2020 says, the autovacuum deamon is enabled, if the postgres config param ‘autovacuum’ is on.

According to this documentation page, autovacuum only runs, if ‘track_counts’ is on.

Run the following sql queries on your db to find out:

SHOW autovacuum;
SHOW track_counts;

On my fresh instance of digital ocean postgres v13 both queries return:

> on

To find out more about the inner cofiguration of autovacuum, you can output other params listed in the above documentation pages, as e.g.:

SHOW log_autovacuum_min_duration;
SHOW autovacuum_max_workers;
SHOW autovacuum_naptime;

Would also like to know! How do we add autovacuum to a DO Managed Database?
