WordPress 2.3 Database Error in post.php

I recently upgraded to WordPress 2.3 and everything worked perfectly fine. However, after running it for a few days, I started encountering this error.

WordPress database error: [Table ‘dhailblog.wp_post2cat’ doesn’t exist]
SELECT cat_ID AS ID, MAX(post_modified) AS last_mod FROM wp_posts p LEFT JOIN wp_post2cat pc ON p.ID = pc.post_id LEFT JOIN wp_categories c ON pc.category_id = c.cat_ID WHERE post_status = ‘publish’ GROUP BY cat_ID
0

This error happens when a post auto saves and is listed below the post. Thankfully I don’t lose the post I’m working on, but i still see the errors…

Any idea whats going on or how to fix it?
