Postgres Extensions 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#
- Go to the Database page in the Dashboard.
- Click Extensions in the sidebar.
- Enable or disable an extension.
note
Most extensions are installed under the extensions schema, which is accessible to public by default. To avoid namespace pollution, we do not recommend creating other entities in the extensions schema.
If you need to restrict user access to tables managed by extensions, we recommend creating a separate schema for installing that specific extension.
Some extensions can only be created under a specific schema, for eg. postgis_tiger_geocoder extension creates a schema named tiger. Before enabling such extensions, make sure you have not created a conflicting schema with the same name.
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.
