How to remove column without downtime with ActiveRecord > 3.0?
...deprecated column names before migration
(basically - hide these columns from AR). This worked because all column
name related methods were based on #columns call
In ActiveRecord starting with 3.1.0 caching of table structures is moved to
ConnectionPool, and all column name related values (e.g. coluumns_hash) are
cached independently.
Is there any way (other than deep-hack of concrete adapters) to achieve
safe column drop in ActiveRecord > 3.0 ?
