Can you give me an example of how to set it up in a Node.js application?

Sure! You can use libraries like node-postgres or mysql2. For example, with node-postgres, you can create a pool like this: const { Pool } = require('pg'); const pool = new Pool({ connectionString: 'your_connection_string' });.

How do I handle errors with connection pooling?

You should implement error handling in your queries and ensure that connections are released back to the pool after use, even in case of errors.
