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.)
