fetchOne returns always numeric-string instead of string|false

            $defaultVersionId = $conn->fetchOne('SELECT id FROM package_version WHERE package_id = :id ORDER BY defaultBranch DESC, releasedAt DESC LIMIT 1', ['id' => $id]);
            \PHPStan\dumpType($defaultVersionId);

Dumped type: numeric-string

From https://github.com/composer/packagist/blob/main/src/Command/PopulateDependentsSuggestersCommand.php#L71

fetchOne returns false if there is no result though.
