We're creating a `merge_access_level` for each `protected_branch`. If a user creates a `protected_branch` while this
|
|
is running, we might be left with a `protected_branch` _without_ an associated `merge_access_level`. The `protected_branches`
|
|
table must not change while this is running, so downtime is required.
