Displaying Posts Using a Custom Select Query showing wrong title

I have created a function as follows:

function get_post_by_custom_field($day) {

global $wpdb;

 $querystr = "
    SELECT wposts.*
    FROM $wpdb->posts wposts, $wpdb->postmeta wpostmeta
    WHERE wposts.ID = wpostmeta.post_id
    AND wpostmeta.meta_key = 'day'
    AND wpostmeta.meta_value = '" . $day . "'
    AND wposts.post_status = 'publish'
    AND wposts.post_type = 'post'
    ORDER BY wposts.post_date DESC
 ";

 $pageposts = $wpdb->get_results($querystr, OBJECT);

if ($pageposts):

  foreach ($pageposts as $post):
    global $post;
    setup_postdata($post);
	//Echo the output
	 the_title();
	echo '<br />';
  endforeach;

endif;

}

Is was taken from the page:

http://codex.wordpress.org/Displaying_Posts_Using_a_Custom_Select_Query

The problem I have is the_title() that is returned are not the title’s of the results – however it is returning the correct ammount of results.

Any help please?
