Right but in this "100-engineer" scenario you'd have hoped the following would have happened:

- Docs and guidelines on migrations would have been written

- Some level of approval and review is required before execution

These are things that isn't really postgres specific, any company that doesn't have those is going to be a nightmare.

If teams have technical boundaries defined at a higher level in the stack (e.g. APIs) and so they don't share a database, you don't need loads of process and docs and architectural meetings to coordinate. Letting teams delivery independently is a good architectural feature.

This is why everyone adopted "microservices" - it's Conway's law in action, a technical intervention for an organizational problem.

Even with those things, blast radius for mistakes is ..the entire company is down.

e.g. User management deploy has somehow taken down core payment processing.
