Подключение к postgresql из node.js
 

Хочу подключиться к БД. порядок действий:
1. создаю с помощью init package.json
2. устанавливаю pg
Код:
const {Client} = require('pg');

const db = new Client({
user:'postgres',
host:'localhost',
password:'12345',
port:5432
})

db.connect()

db.query('SELECT * FROM students',(err, data) =>{
console.log(err, data);
db.end()

})
Запускаю, получаю ошибку:

подскажите, что я делаю не так?

Видимо, пропущен параметр базы данных...

const { Client } = require('pg')

const client = new Client({
  user: 'pgtest',
  host: 'localhost',
  database: 'pgtest',
  password: 'pgtest',
  // port: 3211,
})

client.connect()

client.query('SELECT * FROM test', (err, res) => {
  console.log(err, res)
  client.end()
})

у меня работает...
