Reset user app order back to default order

I am admin on an installation of around 20-30 users. I have ‘app order’ app installed.

I need to reset the custom app order for all users.

Since there is no ability to do this in the UI, can this be done using occ or, worse, a database hack for PostgreSQL?

Thanks.
