Sets up listeners on all tables in a postgres database to be notified of insert/update/delete.
The program tears down listeners once brought down.
You can use this info to display new or updated entries happening to your database in real time as a kind of local monitoring system.
This was driven by the desire to debug DB changes easier for local development.
This program also spins up a small server that allows for a websocket connection to get updates on the DB notifications. You can find a default implementation here
