The TPC-H benchmarks correctly specify that all MONEY columns are DECIMAL type (precision and scale are not specified). We currently use DataType::Float64 which is much lighter than a true Decimal type.
To be a valid benchmark we need to ensure we support the same precision as the reference implementation.
