I thought it was interesting that they upgraded 4 major version numbers in one go. I kept expecting to read something about version compatibility and configuration but was surprised there was none. Are major upgrades like this just less of an issue with Postgres in general?

I think so? PostgreSQL is very well written software AFACT.

I've run into version incompatibilities before, but it was my fault – they were expertly documented in the release notes and I just hadn't read them (or sufficiently tested the upgrade before the live performance of it).
