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
  defaultValue="dashboard"
  values={[
    {label: 'Dashboard', value: 'dashboard'},
    {label: 'SQL', value: 'sql'},
  ]}>

<TabItem value="dashboard">

1. Go to the [Database](https://app.supabase.com/project/_/database/tables) page in the Dashboard.
2. Click **Extensions** in the sidebar.
3. Enable or disable an extension.

  <source
    src="/docs/videos/toggle-extensions.mp4"
    type="video/mp4"
    muted
    playsInline
  />
</video>

</TabItem>

<TabItem value="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`.

:::caution
Enabling some extensions with `create extension <extension-name> with schema extensions` may lead to permission issues (e.g., `dblink`, `http`, `pg_cron`).

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