add_action( 'manage_posts_extra_tablenav', 'admin_post_list_top_export_button', 20, 1 );
function admin_post_list_top_export_button( $which ) {
    global $typenow;
    if ( 'post' === $typenow && 'top' === $which ) {
        ?>
        <input type="submit" name="export_all_posts" id="export_all_posts" class="button button-primary" value="Export All Posts" />
        <?php
    }
}
