Hey guys, just moved to AWS RDS PostGre 16.4 and it seems to be working. I´m on discourse version **3.4.0.beta3-dev** Didn´t press on all buttons, yet 🙂 , but the board itself seems to be working, but… I can´t create backups, due to ```plaintext [2024-12-13 08:36:07] Making sure '/var/www/discourse/tmp/backups/default/2024-12-13-083607' exists... [2024-12-13 08:36:07] Making sure '/var/www/discourse/public/backups/default' exists... [2024-12-13 08:36:07] Updating metadata... [2024-12-13 08:36:07] Dumping the public schema of the database... [2024-12-13 08:36:08] pg_dump: error: server version: 16.4; pg_dump version: 13.18 (Debian 13.18-1.pgdg120+1) [2024-12-13 08:36:08] pg_dump: error: aborting because of server version mismatch [2024-12-13 08:36:08] EXCEPTION: pg_dump failed ``` strange thing is, that I could actually import the data with internal mechanisms: What I did: 1. Set up db (user, database, grants) 2. Configured stuff in app.yml 3. Created backup from within discourse 4. Rebuild app (db migration was successful → db is empty then) 5. Restored backup from within container (launcher enter app, discourse enable\_restore, discourse restore …) 6. Finished (all successful, and everything seemed to be working, until I tried to create a new backup 🙂 ) any chance to tackle this somehow ?
