Row Validation with BQ fails when a primary key column is a timestamp for Oracle, Postgres, Sqlserver and Teradata (MySQL succeeds)

As part of the work on [issue ](https://github.com/GoogleCloudPlatform/professional-services-data-validator/issues/1538) we added an end-to-end validation test for `generate-table-partitions`. Prior tests only generated partition config and didn't run the configs.

The new tests fail on Oracle and PostgreSQL.

Oracle:
```
E TypeError: Arguments approved:boolean and Literal(N):string are not comparable
```

PostgreSQL:
```
E data_validation.exceptions.ValidationException: Some of the validations raised an exception
