How to safely alter Magento category attributes

Question

I understand how to write setup scripts through a custom module. However, if you directly alter something like catalog_category by adding a new attribute, is there a way to then safely remove it in the future, if need be?

I.e. is there way to uninstall a custom module of which has altered core tables?

I'm just a bit wary of editing them if its best practise to stay away all together!

Answer 1

I ended up finding this module. It both helps with uninstallation and understanding the way in which it is achieved (By looking through to module), so doubly helpful!
