Autovacuum to prevent wraparound on ci_builds table takes around
10 hours in production and it can block migrations that try to
lock the table at the same time. This helper can be used to fail
the migration early with a more helpful error message:

```ruby
class RemoveCiBuildsPartitionIdDefault < Gitlab::Database::Migration[2.1]
  enable_lock_retries!

  def up
    fail_if_wraparound_in_progress!(:ci_builds)
    change_column_default :ci_builds, :partition_id, from: 100, to: nil
  end
end
```
