I got the same error shown in logs, and container doesn't start at all. I don't have time to debug it the next few days, so I'll leave everything as is and hope I don't need any bookmarks from the library. EDIT Ok, rollback to v2.14.1 and restore PostgreSQL and Linkwarden from backup works fine to get LW working again. In my case I believe PostgreSQL 12.5 container is to old for the LW v 2.16 but have to verify it in a calm moment. EDIT2 Yes, upgrade to a PostgreSQL 18 did the trick. Now got a running Linkwarden 2.16.
