No, it's MySQL that is doing silent column type changing.
+ My database has an underscore in it's name, and when I grant privileges
+ to a user for this database, a backslash is added before the underscore.
+
+ This is normal and means that the grant is done only for this database. If
+ there was no backslash, this would be a wildcard grant, and the
+ underscore would mean "any character". So, if the database name
+ is "john_db", the user would get rights to john1db, john2db...
+ instead of just john_db.
+ If you really want to grant using a wildcard, there is a dialog box "
+ Database (wildcards allowed)" for this.
