failling CI build

[staabm]

while exploring mutation testing I am stumbling over a failling CI test:

https://github.com/phpstan/phpstan-doctrine/actions/runs/18255085404/job/51975257235?pr=686

There was 1 failure:

1) PHPStan\Platform\QueryResultTypeWalkerFetchTypeMatrixTest::testPgsql with data set "t.col_bool_nullable" (array(array('1', true, null, 0.125, null, '0.1', null, 9, null, '2147483648', null, 'foobar', null, 1, DateTime Object (...))), 'SELECT t.col_bool_nullable FROM %s t', PHPStan\Type\UnionType Object (...), PHPStan\Type\UnionType Object (...), PHPStan\Type\UnionType Object (...), PHPStan\Type\UnionType Object (...), PHPStan\Type\UnionType Object (...), null, null, null, null, null, 'none')

@VincentLanglet is this something you could look into?

Hi, honestly I have no idea about the origin of the failure...

I thought about something related to this bugfix doctrine/dbal#7059,
but looking at the dependencies in 8.1 vs 8.2 it seems like the same doctrine versions are installed...
So I'm not sure what changes.

@janedbal worked a lot on this repository, it might be a better help/have a better knowledge.

It could be great to fix the PHPStan build too https://github.com/phpstan/phpstan-doctrine/actions/runs/17606000257/job/50016842290 (with a baseline ?)
