[Plugin: Peter's Collaboration E-mails] Remove approver_user_id

I personally don’t need the approver_user_id saved in my database, so I just came up with this code to remove it:

/**
 * Remove Peter's Collaboration Emails approver_user_id
 *
 */
add_filter( 'transition_post_status', 'ac_delete_approver_user_id', 11, 3 );

function ac_delete_approver_user_id( $new_status, $old_status, $post ) {

	if ( ( 'pending' == $old_status && 'future' == $new_status ) || ( 'pending' == $old_status && 'publish' == $new_status ) ) {

		delete_post_meta( $post->ID, 'approver_user_id' );

	}

}

It’s untested at the moment, but should work. Just throwing it out there incase anyone else doesn’t want approver_user_id in their postmeta tables either.
