Support - I broke my PostgreSQL Installation

Not intentonaly. Before asking for help I followed this instructions … After installing Joplin : "Error: Postgres version not supported" - #12 by blodarn
But as far as I can tell - I only uninstalled postgresql-16 and didn’t remove the data.

In the logs I saw that immich is forcing a reinstall of postgresql-16 as well and then aborts because there is no response from the set port.
How can I fix that - or is this an upstream (immich) problem?
