Just tested the new Doctrine transport and I've see 3 bugs so far :
- [x] The message is not return by the transport
- [x] The headers column must be of type TEXT and not just STRING
- [ ] When using the PhpSerializer the message is truncated (PR: #30814)

The body in database looks like this :
```
O:36:"Symfony\Component\Messenger\Envelope":2:{s:44:"
```

The body given by the serializer is the following :
```
O:36:"Symfony\Component\Messenger\Envelope":2:{s:44:"Symfony\Component\Messenger\Envelopestamps";a:3:{s:49:"Symfony\Component\Messenger\Stamp\SerializerStamp";a:1:{i:0;O:49:"Symfony\Component\Messenger\Stamp\SerializerStamp":1:{s:58:"Symfony\Component\Messenger\Stamp\SerializerStampcontext";a:0:{}}}s:46:"Symfony\Component\Messenger\Stamp\BusNameStamp";a:1:{i:0;O:46:"Symfony\Component\Messenger\Stamp\BusNameStamp":1:{s:55:"Symfony\Component\Messenger\Stamp\BusNameStampbusName";s:21:"messenger.bus.default";}}s:43:"Symfony\Component\Messenger\Stamp\SentStamp";a:1:{i:0;O:43:"Symfony\Component\Messenger\Stamp\SentStamp":2:{s:56:"Symfony\Component\Messenger\Stamp\SentStampsenderClass";s:64:"Symfony\Component\Messenger\Transport\Doctrine\DoctrineTransport";s:56:"Symfony\Component\Messenger\Stamp\SentStampsenderAlias";s:16:"environment.stop";}}}s:45:"Symfony\Component\Messenger\Envelopemessage";O:34:"App\Message\EnvironmentStopMessage":1:{s:51:"App\Message\AbstractEnvironmentMessageenvironment";O:22:"App\Entity\Environment":5:{s:26:"App\Entity\Environmentid";s:36:"3bade252-b7a9-4188-82bd-3e68129e0da7";s:37:"App\Entity\EnvironmentrepositoryUrl";s:6:"string";s:30:"App\Entity\Environmentbranch";s:6:"string";s:33:"App\Entity\EnvironmenthostNames";a:1:{i:0;N;}s:27:"App\Entity\Environmentenv";a:2:{s:7:"APP_ENV";s:4:"prod";s:7:"APP_VAR";s:13:"example value";}}}}
