@liukun4515 Yes, I'd like to be able to cast() from SQL to these datatypes that are supported by DataFusion functions. Primarily for testing or evaluating behavior or for examples in documentation. Or to load directly from CSV into the unsigned form that Arrow supports (again for testing functions that support those types). Seems DataFusion is used a lot for parquet files -- wouldn't it make sense that if you can select sum(unsigned int), that you could also cast to it? I fully understand and support that we are trying to mirror PG syntax. But I don't think that should prevent us from supporting a superset of data types that PG doesn't. Especially when the support already exists in Arrow and DataFusion functions and we just need this thin shim to extend the support to SQL. -- This is an automated message from the Apache Git Service.
