backup.topic_views
I looks like you did a restore recently and the data before the restore is backup-ed in the backup schema. If you’re certain that you no longer need to recover back to the previous state, you can drop the schema by running the following commands.
./launcher enter app
su - postgres
psql discourse
ALTER SCHEMA "backup" TO "backup-moved";
# Check that you site is still working and up to date
DROP SCHEMA "backup-moved" CASCADE;
