Quick start

A usage example from the pg-pool README.

jsFull README ↗
const Pool = require('pg-pool')

// by default the pool uses the same
// configuration as whatever `pg` version you have installed
const pool = new Pool()

// you can pass properties to the pool
// these properties are passed unchanged to both the node-postgres Client constructor
// and the pool constructor, allowing you to fully configure the behavior of both
const pool2 = new Pool({
  database: 'postgres',
  user: 'brianc',
  password: 'secret!',
  port: 5432,
