Manage Aiven for PostgreSQL® extensions

Aiven for PostgreSQL® allows a series of pre-approved extensions to be installed.

Install an extension​

Any available extension can be installed by the avnadmin user with the following CREATE EXTENSION command:

CREATE EXTENSION EXTENSION_NAME CASCADE;

Update an extension​

To upgrade an already-installed extension to the latest version available, run as the avnadmin user:

ALTER EXTENSION EXTENSION_NAME UPDATE;

To experiment with upgrading, remember that you can fork your existing database to try this operation on a copy rather than your live database.

warning

When a service is updated via a maintenance update, this does not update the extension versions that are used automatically. The reason for this is that user schemas and functions can (and do often) rely on specific versions of an extension being used, so we can't assume that all extensions are safe to upgrade.

Delete an extension​

note

All Aiven service users can delete extensions: both the default avnadmin user and other service users created via the Aiven Console, API, CLI, or Aiven Provider for Terraform. This is the expected behavior because of the extension whitelist configuration in Aiven for PostgreSQL.

To delete an extension, run the following command:

DROP EXTENSION EXTENSION_NAME;

Request a new extension​

We are always open to suggestions of additional extensions that can be useful to many of our customers, and there are a few that can be enabled on request if you need them. For any extensions not on the list of approved extensions, make a request through Aiven Ideas. Be sure to include:

  • which extension is requested
  • which database service and user database should have them
warning

"Untrusted" language extensions such as plpythonu cannot be supported as they would compromise our ability to guarantee the highest possible service level.
