Code review comment for lp:~openerp-dev/openobject-server/6.0-opw-18173-vro

This seems a small change but we don't allow database schema change in the stable branch. If necessary, you can answer with a workaround: use a many2one field instead of a selection field, and make it point to a new custom model with the necessary values. Additionally a widget='selection' can be use on the view for the many2one.
