Postponing the update

If you need to postpone the update during your next rebuild, you can swap the PostgreSQL template on your app.yml file by changing "templates/postgres.template.yml" to "templates/postgres.13.template.yml".

This is not recommended, as some site admins will forget to revert the change afterwards.
