I like my Magento database as clean as possible so whenever I uninstall an extension I also remove all data that was stored by this particular module from the database.
Now I noticed that there is some data stored in the
extra column of the
Admin_User Table too. It lists many old modules that I have removed in the past.
What is the purpose of this column and is it safe to remove the data that is related to exensions that are no longer installed?
