Add cop for use of remove_column remove_column should only be used in the up (or change) step of a migration if it's a post-deployment migration. Otherwise there will be downtime due to the ActiveRecord column cache, which we can avoid by using the IgnorableColumn concern in combination with a post-deployment migration. 2017-12-11 11:34:51 -05:00			`# rubocop:disable Migration/RemoveColumn`
