HI,
I'm trying to understand the utility of pool connection, I found that it's useful to enhance the performance of a database. However I want to know if it is a good option to put a large number in max_connection option to handle a large number of connection in an app?

A couple of hundred connections is already a lot as a point of
contention is snapshot build, which is particularly painful for OLTP
workloads. If you reach a point where you need hundreds of connections,
I would recommend using pgbouncer. This will save your server much CPU
by minimizing the effects of connections still around but idle.
