And type references (like [these](https://github.com/apache/datafusion/pull/10646/files#diff-c7934d272ebcb8a37036a33903e38204a4448dc35f31fea712b4ba9086c12c42R42-R78)) are for different base types, those user-defined types. I'll submit a patch to add document for the usage tomorrow. -- This is an automated message from the Apache Git Service.
