I'm developing a custom xxx_field module which is used in a custom content-type. I started using a renamed version of the field_example and progressed from there.
The problems is that now that I've changed the xxx_field.install and added my own hook_field_schema(), I still have in the DB the old field_example schema.
I've tried deleting all content and reinstalling my xxx_field module, but the DB remains unchanged. I would not like to go by removing all the fields in my custom content-types and adding them after xxx_field reinstall.
