[GitHub] [arrow-datafusion] liukun4515 commented on issue #1379: The data type is not compatible with other system, for example spark or PG database

   In the datafusion, the result type of some function or expr is unsigned numeric datatype. if we use the evaluation result as the `create table  as select xxxx`, we may get some table with unexpected data type compared with the [doc](https://github.com/apache/arrow-datafusion#supported-data-types).
