when uninstalling a module, all instances are deleted from all pages, the database objects are removed (according to uninstall.sql script included with the module) and, if selected, all module files are deleted

Jonathan,

at least with the modules that have set a foreign key to the ModuleId with cascading deletion - and most propably this is a vast majority of modules - this method would not work. As the modules are deleted from the Modules table, all depending records from the module's table(s) would be deleted as well, so if the uninstall script is not run, this would result in some empty tables.

To keep the data I would look for some way to export them, or - using your method - remove the foreign key constraints and/or triggers that delete records in the module's table(s) when records in the core table(s) (Modules, Portals, Users...) are deleted before uninstalling.

Best wishes
Michael
