I am thinking more of cases where you have 100+ customers, and you need to coordinate/connect to each company to perform the upgrade. Doing that every quarter might be a lot of work, and it might be hard to justify for every minor release.

- PGDG publishes release notes.
- PowerShell + Putty(*) are a darned powerful combo for automating remote maintenance.
