By default, when you unistall a module, openerp deletes all data that the module had added to the database. Once in while, I find myself losing data when I mess up with a setting that uninstalls a module. (Yes, there are some settings that are known to remove specific modules) https://github.com/odoo/odoo/issues/2126#issuecomment-5445669

Is there a way I can customize how openerp unistalls a module? I assume I can just override the functions that drops the database tables
