If you're running the nostream relay and a recent version upgrade broke your relay database due to a postresql version mismatch, you can fix it with the following command:

docker compose exec nostream-db psql -U nostr_ts_relay -c "ALTER DATABASE nostr_ts_relay REFRESH COLLATION VERSION"

you'll need to do this while the database container is running (and erroring). you can do this in a second separate terminal window if you'd like to watch the errors stop after the command is ran. good luck.
