Supported PostgreSQL Extensions

To add functionality to your PostgreSQL cluster, you can enable any of the following extensions using psql’s create extension command.

When you connect to a database, you can get a list of the extensions and their versions with this query:

SELECT * FROM pg_available_extensions order by name;

These extensions and versions are current as of the Validated date of this page.

If the extension you need is not on this list, you can suggest it to our product development team using If there’s an existing request for the extension, vote for it and we’ll notify you if we add it in the future. If not, add a new idea and choose Managed Databases as the product category.
