    It look ok to JDBC datasource tough. I am wondering if conversion from `NumericType` to
`StringType` should be prevented or treated for each differently as it looks unsafe for Parquet
and ORC. For example, when column `A` is string, `A >100' will push down a filter with
string value performing string comperison.
