=== Deleting okd copies of pages from the database ===
* Are you trying to hide that you deleted those pages? If so, you will need revision rights, which you need to enable in localsettings.php (see Manual:RevisionDelete). 
* If you're trying to delete archived revisions (but not the history of a page), then Manual:DeleteArchivedRevisions.php. 
* If you're trying to delete page histories, then Manual:DeleteOldRevisions.php.
* There's also an extension that lets you delete pages permanently, without any trace (Extension:DeletePagesForGood). 
* You could also delete their data by accessing the database itself and searching them in the tables they belong to (though you're better off trying the previous options).
