MySQL Syntax Problem w-v2.5.1

After updating from a successfully running v2.5 to v2.5.1, my latest post(s) no longer show up at the top of my post listing, and I get the following message when deleting posts:

WordPress database error You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'WHERE post_id=180' at line 1 for query DELETE FROM WHERE post_id=180 made by post_deleted

Any advice?
