Why is pg library not pulling database from Postgres?

I need to change port to 54023 for it to run on the right port.
**when i print out quiz after trying to pull data, it is empty.
**

db.connect() is not logging any message.

pg library is correctly installed.

I used pgAdmin 4, the Database is named ‘world’. The Table is named ‘capitals’

console.log("query excuted"); is not printed nor did console.log("hi");

import express from "express";
import bodyParser from "body-parser";
import pg from "pg";

const db = new pg.Client({
  user: "postgres",
  host: "localhost",
  database: "world",
  password: "****", 
  port: 54023,
});

const app = express();
const port = 3000;

db.connect()
  .then(() => console.log('Connected to the database'))
  .catch(err => console.error('Failed to connect to the database:', err));

let quiz = [];
console.log('About to execute query');

db.query("SELECT * FROM capitals", (err, res) => {
  if (err) {
    console.error("Error executing query", err.stack);
    console.log("hi");
  } else {
    console.log("query excuted");

    quiz = res.rows;
    console.log(quiz);

  }
  db.end();
});
let totalCorrect = 0;
console.log(quiz);

// Middleware
app.use(bodyParser.urlencoded({ extended: true }));
app.use(express.static("public"));

let currentQuestion = {};

// GET home page
app.get("/", (req, res) => {
  totalCorrect = 0;
  nextQuestion();
  console.log(currentQuestion);
  res.render("index.ejs", { question: currentQuestion });
});

// POST a new post
app.post("/submit", (req, res) => {
  let answer = req.body.answer.trim();
  let isCorrect = false;
  if (currentQuestion.capital.toLowerCase() === answer.toLowerCase()) {
    totalCorrect++;
    console.log(totalCorrect);
    isCorrect = true;
  }

  nextQuestion();
  res.render("index.ejs", {
    question: currentQuestion,
    wasCorrect: isCorrect,
    totalScore: totalCorrect,
  });
});

function nextQuestion() {
  const randomCountry = quiz[Math.floor(Math.random() * quiz.length)];
  currentQuestion = randomCountry;
  console.log(currentQuestion);
}

app.listen(port, () => {
  console.log(`Server is running at http://localhost:${port}`);
});

Well the error initially started with incorrect port number, which i changed. Then the error tells me the question, which is passed on by app.get, does not existed. Then, i looked at the quiz – it turns out it did not pull the database correctly. It is empty. So i look into db.query, it looks like it is not executing each of the lines. Then i look at db.connect(), nothing is printing either?
