> query-based tests are hard to write -- it is unclear how to construct Union or RunEndEncoded types in SQL The way to do so would be via `arrow_cast` However, those types don't seem to be supported via `arrow_cast` yet: ``` > select arrow_cast(1, 'Union(Union))'); Error during planning: Unsupported type 'Union(Union))'. Must be a supported arrow type name such as 'Int32' or 'Timestamp(Nanosecond, None)'. Error unrecognized word: Union ``` -- This is an automated message from the Apache Git Service.
