System Documentation

What problem does it solve?

This Skill solves the problem of efficiently building cache invalidation, job-queue wakeups, or real-time change notifications between PostgreSQL clients without polling, leveraging LISTEN/NOTIFY.

Core Features & Use Cases

  • Real-time Notifications: Delivers payloads asynchronously to listening sessions for guaranteed delivery without replay.
  • Transaction-bound Delivery: Ensures notifications are only sent upon transaction commit.
  • Payload Size Limit Handling: Manages payloads over 8000-byte limit with key-based data fetching.
  • Use Case: A scenario where you need to update a web application with changes in a PostgreSQL database in real-time, such as user profile updates or inventory changes.

Quick Start

Use the postgres-impl-listen-notify skill to listen for 'user_updated' notifications and update the UI accordingly.
