Acctually, #3 is a BIG hit in the preformance of the database;
dreating a new table each time a query is made is hard for the query.
#2 is what I'll be using.
The (one shot) query should be
SELECT p.ID as id_post, * FROM posts wp_posts p, wp_post2cat p2c WHERE
<begin loop> $cat_id (NOT) IN (SELECT category_id FROM wp_post2cat
WHERE post_id = id_post) <end loop>;

This is quite correct, maybe with wrong syntax, but you can get the
idea. This is impossible for our user base, since the minimum
requirement is mysql 2.23, that don't support nesting subqueries.
If you can do this with joins, thats cool, show me how and I can do it
on our code.
