Okay, on my side I have a server for my API, using Drizzle, I guess it already uses some kind of pooling (or at least it asks me to instantiate a pg.Pool, not sure if that's a lightweight connection pooler on the server side), and only a couple of workers with a Drizzle pool each, so I guess I'm far enough from that limit
Do connection increase mostly as you increase microservices / workers, or is it something more related to how many endusers of your service (eg connections on your webserver) you have?
That's exactly right, it's both of those. More containers / services means more connections to the DB, which themselves need to be pooled. More requests to the app require more connections as well.
