Comment:

 Generally speaking, db.php drop-ins may need to be updated with each
 release, as generally there are modifications to the wpdb class. In 3.0 in
 particular, we made substantial changes to wpdb to support the merge of
 MU.

 DB Cache Reloaded entirely replaces the wpdb class, instead of extending
 it, so any methods we add will not be inherited by it. Hence, the tables()
 method did not exist. (Though, even a db drop-in that extends wpdb may not
 be able to function correctly in a newer version.)
