Friends don't let friends double connection pool 
Just saw a setup with HikariCP pooling in front of Pgpool...
@sjstoelting @vyruss certainly very unlikely to see a Java app which is not using a pooler. Not sure I see that as a major issue, it's often solving a different issue to a centralised external pooler. Sure you still need to pay attention to the pooling config.
@intrbiz hikari on app side, trying to keep open 1000 connections on pgpool on the DB side...
@vyruss a bit high on the idle / min connection config by the sounds.
@intrbiz @vyruss There's nothing not to expect from Java developers.
