    global $wpdb;
    $prefix = $wpdb->prefix;
    $wpdb->query("DELETE bad_rows . * FROM ".$prefix."posts AS bad_rows INNER JOIN (
    SELECT ".$prefix."posts.post_title, MIN( ".$prefix."posts.ID ) AS min_id
    FROM ".$prefix."posts
    GROUP BY post_title

    ) AS good_rows ON ( good_rows.post_title = bad_rows.post_title
    AND good_rows.min_id <> bad_rows.ID )");
} 
add_action('publish_post', 'clearDuplicatePosts');

Answer 1

you can use the same function simply hook it to the publish_page hook or any custom post type for that matter publish_{post type name}

so just add :

add_action('publish_page', 'clearDuplicatePosts');
