Rename a model field, how to propagate change to database schema?

How can I rename a field in the model code, e.g. `FooModel`, so that the changes propagate correctly to the database schema?

I would like to rename e.g. `spam` to `beans` in the `FooModel._columns`. But how can I ensure that the same column rename occurs in the database when I update the OpenERP server code?

I can just rename the field in the Python code for the model, of course. But how will Odoo know which field was renamed to what? What if I rename several fields at once? What if I rename one field, delete another, and create another? How can I signal to Odoo which new fields are renames?

For example :

old :
    spam = fields.Char(string='SPAM')

new :

     beans = fields.Char(oldname='spam',string="SPAM")

"oldname" parameter refer to the previous name of this field, so that ORM can rename it automatically at migration.

I rename fields all the time. All that is needed is restarting Odoo, followed by an upgrade of the module that implements the field. Odoo will take care of the schema.
