Bug report

Hello,

in my current work (PHP 8.2), i have used (for the first time) PDOStatement::getIterator() for a custom Repository :

protected function executeIterator(string $sql, array $params = []): \Iterator
{
    $stmt = $this->dbConn->prepare($sql);
    $stmt->execute($params);
    
    return $stmt->getIterator();
}

The following error occurs when i run phpstan:

AbstractRepository::executeIterator() should return Iterator but returns Traversable<mixed, array<int|string, mixed>>

But according to the documentation, PDOStatement::getIterator returns an Iterator:

public PDOStatement::getIterator(): Iterator

Code snippet that reproduces the problem

Here the URL of a snippet : https://phpstan.org/r/1043c9a2-812c-4a95-bdac-e89b4c865656

Expected output

This error should not be displayed.

Did PHPStan help you today? Did it make you happy in any way?

Ho yes it helps me a lot ! And not only today !

I had once a migration from an older PHP version to PHP 8 and PHPStan was fundamental in my work.
I am no sure i could have done this migration without it!

So many thanks for your work !!

Your work is so helpful that i cannot imagine working without PHPStan !

Thank you again !
