DCHECK_Lt might be better here.

I don't think it would change anything. Or we would have to do a full-blown check for valid values, which is a bit out of scope.

OK. I think it prevents accidental writes of UNDEFINED as well.

ConvertedType::NA corresponds to an invalid converted type that was once added to the Parquet spec: apache/parquet-format#45 but then quickly removed in favour of the Null logical type: apache/parquet-format#51 Unfortunately, Parquet C++ could still in some cases emit the unofficial converted type. Also remove the confusingly-named LogicalType::Unknown, while "UNKNOWN" in the Thrift specification points to LogicalType::Null.
