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
- Dashboard
- SQL
- Go to the Database page in the Dashboard.
- Click Extensions in the sidebar.
- Enable or disable an extension.
-- Example: enable the "pgtap" extension and ensure it is installed
create extension pgtap with schema extensions;
-- Example: disable the "pgtap" extension
drop extension pgtap;
Even though the SQL code is create extension, this is the equivalent of "enabling the extension".
To disable an extension call drop extension.
caution
Enabling some extensions with create extension <extension-name> with schema extensions may lead to permission issues (e.g., dblink, http, pg_cron).
Full list of extensions
Supabase is pre-configured with over 50 extensions. You can also install your own SQL extensions directly in the database through our SQL editor.
