I like Supabase's approach over pub/sub. One of the big advantages is they listen to the Postgres WAL which overcomes the 8000 bytes limitation[1] of the notify approach.

And Elixir is especially well suited for this type of workload. I actually extracted out much of the Supabase Realtime library so that I could work with the data directly in Elixir[2]
