How to display a sortable column with post IDs in the WordPress admin?

Question

PHP

Good afternoon.
I'm trying to display a sortable column with post IDs in the wordpress admin.
/* Adding a column with IDs of posts and pages to the admin */ Source

function true_id($args){
  $args['post_page_id'] = 'ID';
  return $args;}
function true_custom($column, $id){
  if($column === 'post_page_id'){
    echo $id;   }}
add_filter('manage_pages_columns', 'true_id');
add_action('manage_pages_custom_column', 'true_custom',10, 2);
add_filter('manage_posts_columns', 'true_id');
add_action('manage_posts_custom_column', 'true_custom',10, 2);

ID are displayed - everything is ok.
/* add the ability to sort the column */ Source

add_filter('manage_edit-post_sortable_columns', 'add_views_sortable_column');
function add_views_sortable_column($sortable_columns){
  $sortable_columns['post_page_id'] = 'views_views';
  return $sortable_columns;}

It becomes possible to sort by the ID column, when pressed, the line looks like:
/wp-admin/edit.php?orderby=views_views&order=desc
But in fact, sorting occurs not by the "ID" field, but by the "Date" field.
What could be the problem?
Thank you for your reply.
