@lubennikovaav to enable it

[vadim2404]

to move this extension to our docker image

[andreasscherbaum]

It's already in the Docker image, then release compute image, then enable background worker.

[andreasscherbaum]

Not in the old compute image which is currently pinned, we need to roll out new compute first.

@save-buffer Please confirm that this is available now, and what other work is still required.

Will be available once https://github.com/neondatabase/cloud/pull/11795 merges

[save-buffer]

It merged so it should be available with the next compute release
