This attribute is misleading as it is insufficient to correctly upgrade the database. It only renames the column in the database, but other operations are needed, like updating the corresponding `ir.model.fields` record (and its xmlid). The default values and the translations are also lost during the upgrade. Moreover, this feature was misused. It was: - left on fields during multiple versions. - used on reports (SQL views). This would be ok if the feature was complete, but, as is, it was useless. - kept unchanged after a second renaming of the field (which can happen versions later the first rename). - used, even when the meaning of the field changed. i.e. the field `archived` has been renamed to the classic `active`, but the value in the database should be switched.
