This is a side point but the docker suggestion is far cleaner if you work on multiple apps as you can easily configure and run multiple versions with Dockerfiles and compose files to be exactly right for each app, with only the plugins the specific app needs, data stored in a custom location for each app, and the ability to turn off postgres for an app. System postgres installs and upgrades are a needles pain for development.

But I agree that's nothing to do with brew conversation.

Not just different apps but having multiple working environments for the same app - very useful when you wreck the db on a feature branch and need to jump to another to fix a bug etc.
