Same problem here :

'sale_order_id': fields.many2one('sale.order', 'Sale Order',
on_delete='cascade', readonly=True),


constraints are not generated. This is a serious problem and should not be listed as 'wishlist'.

Title:
  ondelete='cascade' constraint not generated in postgres

Status in OpenERP Server:
  Triaged

Bug description:
  class dimu_settlement_portal_all(osv.osv):
      _inherit = "dimu.settlement_portal_all"

  ....
  { 'csv_file_id' : fields.many2one
               ('holophon.csv_files','CSV file', select=True, required=True, readonly=True, ondelete='cascade'),

  the constraint is not generated in postgres.

  we had some problems, because the filed was NULL  initially, but even
  after fixing it the constraint is not generated during update of the
  module.
