Research direction

Start in datafusion/expr/src/utils.rs at the linked lines and inspect the method that checks whether DataTypes support hashing. Compare its behavior with the DataTypes defined in the project and locate any related tests. Done means the hash-support check is confirmed or updated to match the supported DataTypes, with coverage for the relevant cases.
