Comment (by Denis-de-Bernardy):

 $wpdb->posts.* might even be useful in some cases, in case someone
 retrieves extra fields with one or more left joins on $wpdb->postmeta.

 alternatively, we'd need:

 {{{
 $count_fields = apply_filters('count_fields', "$wpdb->posts.ID");
 }}}

 or something like that... in order to retrieve the correct number of
 posts.
