Database Webhooks act as a wrapper around PostgreSQL triggers, asynchronously emitting HTTP GET and POST requests whenever table data is inserted, updated, or deleted. The networking layer relies on a new PostgreSQL extension called pg_net, which pairs a PostgreSQL background worker queue with libcurl to handle multiple concurrent outbound requests without blocking SQL queries. Although pg_net currently processes over 300 requests per second, Supabase plans to expand capabilities to include direct triggers for AWS Lambda and Google Cloud Run before launching dedicated Supabase Functions."

# Updates for Supabase Functions

**Type:** Announcement

## Summary

Supabase has announced an Alpha release of Database Webhooks alongside dashboard management tools for native PostgreSQL Functions and Triggers. Database Webhooks act as a wrapper around PostgreSQL triggers, asynchronously emitting HTTP GET and POST requests whenever table data is inserted, updated, or deleted. The networking layer relies on a new PostgreSQL extension called pg\_net, which pairs a PostgreSQL background worker queue with libcurl to handle multiple concurrent outbound requests without blocking SQL queries. Although pg\_net currently processes over 300 requests per second, Supabase plans to expand capabilities to include direct triggers for AWS Lambda and Google Cloud Run before launching dedicated Supabase Functions.

## Context

Supabase users, particularly Enterprise and Jamstack developers, requested the ability to trigger existing serverless functions and API routes directly from database events without vendor lock-in. Managing raw PostgreSQL functions and triggers was also difficult without dedicated dashboard interfaces.

## Approach / What changed

Supabase introduced a native functions editor and trigger interface in the Dashboard, while launching Database Webhooks in Alpha. To support asynchronous HTTP dispatch from triggers without slowing database operations, Supabase developed the pg\_net extension, which uses a PostgreSQL background worker and the libcurl multi interface to queue and execute non-blocking HTTP requests.

## Takeaways

- Supabase developed pg\_net, an asynchronous PostgreSQL networking extension that uses background workers and libcurl to send HTTP requests at over 300 requests per second.
- Database Webhooks capture INSERT, UPDATE, and DELETE row changes as triggers to deliver structured payloads matching Supabase Realtime format without needing an active client listener.
- The Supabase Functions rollout roadmap is staged across external HTTP webhooks, native AWS Lambda and Google Cloud Run execution via restricted IAM roles, and native Supabase Functions.
