Documentation is confusing

Here https://docs.sentry.io/server/queue/ it says that BROKER_URL should be with database number at the end, but here https://github.com/getsentry/sentry/blob/releases/8.7.x/src/sentry/conf/server.py it’s without /0 at the end. Which is right?

For Redis, that last value is the database number. If it’s missing, 0 is implied.

So it’s doesn’t matter. Thanks
