Hi Emi,

As far as I know, it wont affect your performance.

It will affect the overall quantity of users that can connect to the database though (since there is a limit that you can set up on postgres.conf).

BR,

Felipe

Maybe your application is using a pool of 10 connections but it doesn't
affect any potential performance issues.
