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!
