WordPress's Auto-Save feature is a really nice but there are some drawbacks... this feature increases your database usage. So for those of you that are on really bad shared hosting accounts or just want to turn it off, here's a quick way of doing it.

Open and insert the following line in your wp-config.php file.

define('WP_POST_REVISIONS', false);

Another method is to remove all of the entries from the database from time to time. You can do tun this query to do it::

DELETE FROM wp_posts WHERE post_type = "revision";
