WordPress Post Revisions
Too much post revisions will increase the WordPress database storage. Revisions are full copies of the post. If want to decrease the database size, limit the how many revisions should be saved is a good option.
Add the code below in config.php
define( 'WP_POST_REVISIONS', 3 ); //Only 3 post revisions will be stored
Old version of revision will be deleted once the post is updated again.
