(

)

Does the script need different DB access? By default, we give Maintenance scripts normal rights to the DB.

Sometimes, a script needs admin rights access for a reason and sometimes they want no access. Subclasses should override and return one of the following values, as needed: Maintenance::DB_NONE - For no DB access at all Maintenance::DB_STD - For normal DB access, default Maintenance::DB_ADMIN - For admin DB access

Returns:

Integer
