Comment:

 Nacis is right. It does indeed split the query with external object cache
 so the patch is pretty useless. However, after a little more debugging it
 turned out that string replacement in alias_posts_table() breaks the
 `"$wpdb->posts.*" == $fields` assumption in WP_Query, thus explicitly
 setting $split_the_query to false :(

 To reproduce add the following before running a next post query with
 external object caching:

 {{{
 add_filter( 'get_next_post_where', function( $where ) { return $where; }
 );
 }}}
