    At times we need to change the message that is displayed after a node is saved.Follwing code helps to customize using form_alter.

    function mymodule_form_alter(&$form, &$form_state, $form_id) 
    {
        if($form['form_id']['#value'] =='formvalue')
        {   
              if($form['buttons']['submit']['#submit']){
                $form['buttons']['submit']['#submit'][] = 'mymodule_submit_function';
              }
        }
    }
    
    function mymodule_submit_function($form, &$form_state){
    
        global $_SESSION;
        $insert = empty($form_state['values']['nid']);
        if($insert){
            //Write your custom message text here
            if($form['nid']['#post']['form_id'] == 'formvalue'){
                $keys = array_keys($_SESSION['messages']['status']);
                $last_key = end($keys);
                $message = 'My custom messge after node save';
                $_SESSION['messages']['status'][$last_key] = $message;
            }
        }
    }
