I logged in. Haven’t updated in 11 months. Started with trying to upgrade the Docker Manager. It never seemed to complete. Next day the admin page was pretty much borked. I tried to do the ./launcher rebuild app. I get the

If you haven’t seen the topic PostgreSQL 15 update - Announcements you might start there. It discusses a number of issues and recommendations.
