Issue:
ConversionException formats non-string scalar values as strings
The following types are converted incorrectly:
1. Could not convert PHP value '123' of type 'integer' […]
2. Could not convert PHP value '-123' of type 'integer' […]
3. Could not convert PHP value '12.34' of type 'double' […]
4. Could not convert PHP value '1' of type 'boolean' […]
5. Could not convert PHP value '' of type 'boolean' […]

The issue was discovered and suppressed in https://github.com/doctrine/dbal/pull/4319.
