If I understnad right, they are saying it scales (to theri needs) with a custom patch to pg changing their semantics, right?

It does seem interesting, and possibly welcome if there were a configuration option or even a way to set individual notifies as serialized or not.

To be clear, it's not a custom patch to pg itself, but an application-side buffering and batching optimization.

Ah, thanks. I am not following at all how an application can do this.
