When it comes to database connection pooling, my approach is pretty straightforward.

Hey everyone, I've been thinking about connection pooling a lot lately, especially with our services scaling up. We're running into some issues with contention and wanted to see how you all are tackling it. Are you sticking with the built-in pooling that comes with your ORM or driver, or do you like using a separate external pooler, like PgBouncer? What have you found are the pros and cons of each, and what kind of stats do you keep an eye on to make sure your pooling is actually working well?
