Using stringable object as query parameter fails

[janedbal]

$dbalConnection->fetchAssociative('
    SELECT *
    FROM bar
    WHERE foo = :enum
', [
    'enum' => new Enum('foo'),
]);

Causes error:

Uncaught staabm\PHPStanDba\DbaException: Unexpected expression type PHPStan\Type\ObjectType in /app/vendor/staabm/phpstan-dba/src/QueryReflection/QuerySimulation.php:91

Even though the Enum has __toString method which works fine in dbal query.

thx for reporting. this is obviously a bug and should work.

Atm we are php8+ only, so we could utilize the stringable interface
https://www.php.net/manual/en/class.stringable.php

for the impl we need a new instance-of check here

phpstan-dba/src/QueryReflection/QuerySimulation.php

Line 30 in 4d1c84b

public static function simulateParamValueType(Type $paramType, bool $preparedParam): ?string

Testcase can be added at the bottom of https://github.com/staabm/phpstan-dba/blob/main/tests/data/pdo-prepare.php
