How can I handle errors in Node.js with PostgreSQL?

You can handle errors in Node.js with PostgreSQL by using try-catch blocks and checking for error codes.

Can you give me an example of using try-catch with PostgreSQL?

Sure! Here's a simple example:

const { Client } = require('pg');
const client = new Client();

async function queryDatabase() {
    try {
        await client.connect();
        const res = await client.query('SELECT * FROM users');
        console.log(res.rows);
    } catch (err) {
        console.error('Error executing query', err.stack);
    } finally {
        await client.end();
    }
}
queryDatabase();

What should I do if I get a connection error?

If you get a connection error, check your database credentials, ensure the database server is running, and verify network settings.
