SQL statements are interpreted by an engine. One engine may need to do a
rebuild of a full table, another may not.
If an engine can just "add" a column, then the action for it may just be "add
column". If another engine needs to copy/rename/delete then it will have a
different set of actions.
We need to be descriptive about the change, but the actual mechanics are up to
the individual engine.
