# Normally we don't process background migrations in a regular migration, as
# this could take a while to complete and thus block a deployment.
#
# In this case the jobs have all been processed for GitLab.com at the time
# of writing. In addition, it's been a few releases since this migration was
# introduced. As a result, self-hosted instances should have their
# migrations finished a long time ago.
#
# For these reasons we clean up any pending jobs (just in case) before
# deploying the code. This also allows us to immediately start using the new
# setup only, instead of having to support both the old and new approach for
# at least one more release.
