Reopening, this query currently fails with:

thread 'tokio-runtime-worker' panicked at 'false_values downcast failed', datafusion/src/physical_plan/expressions/case.rs:216:30
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
Error: ArrowError(ExternalError(ArrowError(ExternalError(Execution("Arrow error: External error: oneshot canceled")))))

No longer errors
