This is cool, but this sort of proves my point to friends that Postgres isn't "production ready" out of the box, you need all kinds of tooling around it to make it so.
“Production ready” is context-dependent. If you have no need of particular features, it may make sense to not have them installed for a number of reasons.
Can you speak more on what you think is missing? Looking at the repo I semi-regularly deploy grafana (which I'd argue should never be part of core postgres) and pgbackrest (I wouldn't hate having more sophisticated backup built-in). I once deployed citus for an application that needed it's special talents. In general I'd say my production use of postgres has been pretty vanilla.
