Widget queries even when there are no sidebars?

Question

I'm trying to reduce my database queries. I don't have any sidebars or widgets set but I noticed the following query

SELECT option_value FROM wp_options WHERE option_name = 'widget_pages' LIMIT 1

Similar queries happen for widget_calendar, widget_links, widget_tag_cloud, and widget_nav_menu.

5 database queries for no reason. How do I disable this?

remove_action('widgets_init') doesn't do anything.

Answer 1

Does unregistering them the also disable the database queries?

Goes in functions.php:

//Unregister all Default Widgets

function unregister_default_wp_widgets() {
    unregister_widget('WP_Widget_Pages');
    unregister_widget('WP_Widget_Calendar');
    unregister_widget('WP_Widget_Archives');
    unregister_widget('WP_Widget_Links');
    unregister_widget('WP_Widget_Meta');
    unregister_widget('WP_Widget_Search');
    unregister_widget('WP_Widget_Text');
    unregister_widget('WP_Widget_Categories');
    unregister_widget('WP_Widget_Recent_Posts');
    unregister_widget('WP_Widget_Recent_Comments');
    unregister_widget('WP_Widget_RSS');
    unregister_widget('WP_Widget_Tag_Cloud');
}
add_action('widgets_init', 'unregister_default_wp_widgets', 1);

Answer 2

I have the following code in a theme, it stops any related db queries from running.

function unregister_all_default_wp_widgets() {
   // list the default WordPress widgets here
}
add_action('widgets_init', 'unregister_all_default_wp_widgets', 1);
