Sean McGivern	1ab33b15d1	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 16:34:51 +00:00
