I guess readonly=True and ondelete='cascade' create a conflict.

....
{ '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.
