Jira issue originally created by user adrive:
I ran all tests with PostgreSQL and I got an error:
1) Doctrine\Tests\DBAL\Functional\TypeConversionTest::testIdempotentDataConversion with data set #3 ('bigint', 12345678, 'string')
The expected type from the conversion to and back from the database should be string
Failed asserting that <integer:12345678> is of type "string".
Tests: 367, Assertions: 745, Failures: 1, Skipped: 8.
The BigInt Type is missing convertToPHPValue() method and returns string instead of int. I fixed this and also I fixed the test case for this. Patch will be availabe via github pull request.
Comment created by @beberlei:
Bigints have to be strings for int overflow reasons. PostgreSQL seems to detect 64 vs 32bit systems and casts correctly, this is unfortunate for the tests, i have to come up with a workdaround for this :-)
Issue was closed with resolution "Won't Fix"
Comment created by heruan:
This behavior can't be correct:
php > var_dump($object->id);
php > $em->persist($object);
php > vardump($em->find(getclass($object), 201308090001)->id);
The type should be consistent no matter what, otherwise the idempotent requirement breaks.
[~heruan] This was fixed, bigint identity generation will always work with strings.
