People say you don’t need Redis, you can just use Postgres LISTEN/NOTIFY. I read a blog post about it locking the entire database and causing problems[0]. Apparently it’s fixed now but this only just being discovered in 2025 doesn’t give me confidence it’s battle tested for prod.

At some point shoving everything into Postgres is an anti pattern too.
