I was wondering how to remove my post revisions while I’m still developing a website. So I ended up with the following code:
You can manage your post revisions using the following global variable:
You can clean up your database by the following query:
DELETE a,b,c FROM wp_posts a LEFT JOIN wp_term_relationships b ON (a.ID = b.object_id) LEFT JOIN wp_postmeta c ON (a.ID = c.post_id) WHERE a.post_type = 'revision';
Thanks to this post.
