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.
