Nuxeo unironically used a db table as a pub sub system between the cluster nodes for cache invalidations.

It’s not so out of the ordinary. A few libraries in Rails create message queues in Postgres using advisory locks and listen/notify.

Hell, if it’s not an RDBMS then it’ll be Redis (at a much greater expense for a managed instance). I’ve seen that setup in the Ruby world far more often than using a dedicated message queue.
