> RecordReaderImpl::pickRowGroups() will check if filter-column is safe for ppd evaluation with file column id, but the parameter of SchemaEvolution::isPPDSafeConversion is reader column id, which is different from file column id, and this causes pushed filters can't be evaluated and recordReader can't skip row groups which are not matched.
