UPDATE EXTENSIONS

The UPDATE EXTENSIONS statement allows to synchronize the local installed extension state with the repository that published a given extension. This statement is the recommended way to keep up to date with new feature or bug fixed being rolled out by extension developers.

Note that DuckDB extensions cannot be reloaded during runtime, therefore UPDATE EXTENSIONS does not reload the updated extensions. To use the updated extensions, restart the process running DuckDB.

Updating All Extensions

To update all extensions installed for DuckDB version of your client:

UPDATE EXTENSIONS;

This will iterate over the extensions and return their repositories and the update result:

┌────────────────┬──────────────┬─────────────────────┬──────────────────┬─────────────────┐
│ extension_name │  repository  │    update_result    │ previous_version │ current_version │
│    varchar     │   varchar    │       varchar       │     varchar      │     varchar     │

Updating Selected Extensions

For more fine-grained control, you can also provide a list of extension names to be updated:

UPDATE EXTENSIONS (name_a, name_b, name_c);

How It Works

UPDATE EXTENSIONS is implemented by storing, if available, the ETag information, and sending a GET request conditional on the fact that the remote extension is different (using the ETag as proxy) than the local available one. This ensures that subsequent UPDATE EXTENSIONS calls – if the remote state has not changed – are inexpensive.

If a change is found for a given extension, DuckDB performs the following operation. For example, if name_a and name_c changed, then:

UPDATE EXTENSIONS (name_a, name_b, name_c);

This will result in the following commands:

FORCE INSTALL name_a;
FORCE INSTALL name_c;
