Errors with PostgreSQL

Hello,
I've found some problems using menu_stp with PostgreSQL (8.2). First, the install-Script does not create the needed table, Fix for this would be like:

menu_stp.install:

case 'pgsql':
  db_query("CREATE TABLE menu_stp_roles (mid INT NOT NULL, rid INT NOT NULL, PRIMARY KEY (mid, rid))");

Second Problem is the insert in menu_stp_form_submission (menu_stp.module), only did this quick fixes to make it work for me, maybe it helps you in further development.

if($sel && !$hasp) { // role gets permission
  switch ($GLOBALS['db_type']) {
    case 'mysql':
    case 'mysqli':
      db_query("INSERT INTO {menu_stp_roles} (`mid`,`rid`) VALUES ('$form[mid]','$rid');");
    break;
    case 'pgsql':
      db_query("INSERT INTO {menu_stp_roles} (mid,rid) VALUES ('$form[mid]','$rid');");
    break;
  }
