How to set ModerationInformation.Status Values in Powershell?

Question

I have saved $item.ModerationInformation.Status information in HashTable $DeletedItemsIDs and recycled list items. After That I restored items from recycle bin and assign saved ModerationStatus information back to items, but items restored with "Pending" status. Whats wrong with this Powershell code? I can see the correct saved Moderation status info in variable $deleteditemId.Value

    // Saving Modeartion status info
  $DeletedItemsIDs = @{}

    foreach($item in $ListItems)
    {
       $DeletedItemsIDs.Add($item.ID,$item.ModerationInformation.Status)
       $DeletedItem = $item.recycle()       
       $DeletedItems.add($DeletedItem)
    }


// I do some stuff here and then restore as 

ForEach ($deletedGuid in $DeletedItems)
{
 $site_To_AddCT.RecycleBin.Restore($deletedGuid)
 $Recount++
}
    //Here assigning back moderation status info after restoring


      ForEach ($deleteditemId in $DeletedItemsIDs.GetEnumerator())
      {

       $Pageitem = $PagesLibrary.GetItemById($deleteditemId.Key)
       $Pageitem.File.CheckOut()
       $Pageitem["ContentTypeId"] = $Global:ctToAdd.Id
       $Pageitem.File.CheckIn("CheckIn automatically")
       $Pageitem.File.Publish("Published automatically")
       $Pageitem.ModerationInformation.Status = $deleteditemId.Value // whats wrong here
       $Pageitem.Update()
     }

Add $Pageitem.Update() (or .SystemUpdate()) after assigning ModerationInformation.Status:

$Pageitem.Update();

You need to update the item after changing the metadata as well as after setting the Moderation Status. Your code should look like this:

$Pageitem = $PagesLibrary.GetItemById($deleteditemId.Key)
$Pageitem.File.CheckOut()
$Pageitem["ContentTypeId"] = $Global:ctToAdd.Id
$Pageitem.File.CheckIn("CheckIn automatically")
$Pageitem.File.Publish("Published automatically")
$Pageitem.Update(); //I would use SystemUpdate(false); this won't increase the file version.
$Pageitem = $PagesLibrary.GetItemById($deleteditemId.Key)
$Pageitem.ModerationInformation.Status = $deleteditemId.Value
$Pageitem.Update(); //Maybe SystemUpdate(false) here as well, depending on the requirements
