NameError: uninitialized constant ProgressBar trying to refresh foreign tables

Consider:

$ sudo gitlab-rake geo:db:refresh_foreign_tables
rake aborted!
NameError: uninitialized constant ProgressBar

Seen in GitLab v10.8.1-ee.0 on gprd.

Perhaps some rake tasks are missing the environment prerequisite (which enables autoloading), or perhaps some .rake files need require "progressbar" adding to them?
