Bug report

When using a PDOStatement with mode PDO::FETCH_COLUMN I want to be able to type the statement with the appropriate type for the column, e.g. @var PDOStatement<int,string>.

For PHPStan versions up to 2.1.38, this works correctly and no errors are reported. From PHPStan 2.1.39 onwards, this now reports:

PHPDoc tag @var contains unresolvable type.
🪪  varTag.unresolvableType

Expected output

No errors found.
