hi @ziln :wave: welcome to discourse meta :slight_smile: [image] ziln: ERROR: type “ai_moderation_setting_type” already exists EXCEPTION: psql failed: ERROR: type “ai_moderation_setting_type” already exists i think it looks like your target instance isn’t clean or has data already, and you’re getting an object collision. assuming this is a standard install, try dropping and creating a clean new database, then doing the migration. looks like pfaffman had a similar issue here: [image]Restore failed `entity2char already exists' RDS Postgres 13.7 The solution was to drop, create, and migrate the database before doing the restore. I should have tried skipping the migrate step.

I don’t know. That guy doesn’t sound like he knows much. :wink:

thanks for your input :slight_smile: Yes, I’ve tried droping and creating new db but I got the same error. I was only able to restore backup via SQL manually.
