Comment (by filosofo):

 A filter might still be worthwhile, but most folks who want to tweak wp-db
 create a new db class that inherits from wpdb and replaces methods it
 wants to change.

 I'm trying to understand how that would work.  Since the wpdb class is
 instantiated as $wpdb before plugins are loaded (and therefore before any
 potential child classes), wouldn't any attempt to replace a wpdb method
 (as instantiated in $wpdb) be fruitless?
