## Description

The existing code snippet is as follows:
```php
$code = $exception->errorInfo ? $exception->errorInfo[1] : $exception->getCode();

switch (true) {
    case 'pgsql' === $driver && '42P01' === $code:
```

When we print `$exception->errorInfo[1]`, it yields 7, which is interpreted as false. This behavior has been rectified.

**Additionally, this pull request fixes the integration tests that have been failing persistently until now.**
