Listen to Database Changes Through the Postgres WAL
Worth mentioning that WAL is enabling and used by Supabase Realtime [0] and WalEx [1] which both are doing very similar thing - polling the WAL changes in order to emit them as Websocket events.
I never worked with WalEx but have experience with Supabase Realtime and it is a joy to work with and fits great into the Supa ecosystem. So many layers are disappearing when you rely more on Postgres!

New Observability Features in Supabase
We are starting to add OpenTelemetry support to all our core products and our Telemetry server. OpenTelemetry (OTel) standardizes logs, metrics, and traces in a vendor-agnostic format, so you can ingest data into tools like Datadog, Honeycomb, or any monitoring solution you already use. While you'll still have the freedom to bring your own observability stack, we're preparing to surface this data natively in the Supabase dashboard.
