How can I handle connection pooling errors in Node.js?

You can handle connection pooling errors in Node.js by using try-catch blocks and monitoring the pool's events.

What specific events should I listen for in the connection pool?

You should listen for 'error' and 'acquire' events to manage errors and track when connections are acquired.

Can you provide a code example for that?

Sure! Here's a simple example:

const { Pool } = require('pg');
const pool = new Pool();

pool.on('error', (err) => {
  console.error('Unexpected error on idle client', err);
});

pool.on('acquire', (client) => {
  console.log('Client acquired');
});

What should I do if the pool runs out of connections?

If the pool runs out of connections, you can increase the pool size or implement a retry mechanism for your queries.
