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
|
|
|
|
<Tabs
|
|
scrollable
|
|
size="small"
|
|
type="underlined"
|
|
defaultActiveId="dashboard"
|
|
>
|
|
<TabPanel id="dashboard" label="Dashboard">
|
|
|
|
1. Go to the [Database](https://supabase.com/dashboard/project/_/database/tables) page in the Dashboard.
|
|
2. Click **Extensions** in the sidebar.
|
|
3. Enable or disable an extension.
|
|
|
|
</TabPanel>
|
|
<TabPanel id="sql" label="SQL">
|
|
|
|
```sql
|
|
-- 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`.

|
|
|
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.
