Is server side pooling necessary for Sequlize pool to work?

Question

I have a nodejs application and I am using sequelize as ORM with Postgres. As explained in documentation of sequelize, here is my code for pooling.

const sequelize = new Sequelize(/* ... */, {
  // ...
  pool: {
    max: 10,
    min: 0,
    acquire: 30000,
    idle: 10000
  }
});

Since Postgres doesn’t have inbuilt pooling (AFAIK), Do I need to install and configure something like pgbouncer, on my server to make pooling work?

Answer 1

No. Having multiple levels of pooling rarely makes sense, and you can certainly have a client-side pool without a server-side one.
