Overview

Extensions are exactly as they sound - they "extend" the database with functionality which isn't part of the Postgres core. Supabase has pre-installed some of the most useful open source extensions.

Enable and disable extensions#

1. Go to the Database page
2. Click on "Extensions" in the sidebar
3. Find the extension you would like to enable/disable
4. Click the toggle.

Full list of extensions#

Supabase is pre-configured with over 50 extensions. You can also install your own SQL extensions directly into the database through our SQL editor.
