I already have a Node.js application using NestJS with TypeORM configured. Now, I want to implement a PostgreSQL connection pool using pg Pool for better database connection handling. Is it possible to integrate this into my existing setup, or do I need to start from scratch?

I have also created a separate Node.js NestJS project from scratch where I implemented pg Pool, and it's working fine. Now, I would like to know how I can achieve a similar setup using TypeORM configurations.
