When adding a "Custom Column" to your library, you create a database field. But what if you made a mistake and don't realize it until after you hit "Apply" and restart Calibre?

I did this. The type of column I added doesn't perform the way I thought it would (newbie mistake). There is no data in this field, and I know I don't have to display or use the field. But is there some method for fixing mistakes like this?

Being able to change the names would be a nice way to recycle the column. Being able to change the type of field this is would probably be impossible. But if you have a totally empty field, getting rid of it completely would be a nice do-over option. Any choices available for fixing these mistakes, other than creating a new library and copying all my books to the "improved" version?
