As Mentioned by Denys Séguret in Answer, the function query.on is deprecated. And if you are a beginner and want to get a quick connection to try out your queries without being bothered by async/await functionality. You can try the below code:-

const { Pool, Client } = require('pg')
const connectionString = 'postgresql://dbuser:dbpassword@database.server.com:5432/mydb'

const pool = new Pool({
  connectionString: connectionString,
})

pool.query('SELECT NOW()', (err, res) => {
  console.log(err, res)
  pool.end()
})
