You will need to include this query in your installation part of your product:

PHP Code:

$db->query_write("UPDATE " . TABLE_PREFIX . "forum SET allowsig = 1"); 


You ought to consider altering:

PHP Code:

$db->hide_errors();
$db->query("ALTER TABLE " . TABLE_PREFIX . "forum ADD allowsig SMALLINT( 3 ) UNSIGNED NOT NULL DEFAULT '1'");

$db->query = "ALTER TABLE `".TABLE_PREFIX."forum` ADD (
  `allowsig` smallint(3) NOT NULL default '1')";
$db->show_errors(); 


so that query becomes query_write

Also - Since you have a Control Panel Global phrase there is no need for the second phrase
