The promise of digital mapping is to provide a shared and real-time view of the state of the underlying system.

pg_eventserv is a free and open-source component that helps fulfill the promise of real-time event modeling and shared views in PostgreSQL.

By connecting to PostgreSQL and listening on specified channels, pg_eventserv captures database notifications and forwards them to web clients, enabling real-time updates and synchronization of data displayed on maps or other web interfaces.

pg_eventserv does one thing and one thing only: take events generated by the PostgreSQL NOTIFY command and passes the payload along to waiting WebSockets clients.

pg_eventserv is free and easy to install and you can find it here: https://github.com/CrunchyData/pg_eventserv

What this means is that any client can watch for notifications and update as changes in the database happen.

Real-time data!

Here is a link to a Youtube video demonstration of pg_eventserv in action!

I will let Paul Ramsey the creator of pg_eventserv explain all this in more detail in this episode.
