This is fixed in version 54:
```
% datafusion-cli
DataFusion CLI v54.0.0
> WITH RECURSIVE chain AS (
SELECT 'A' AS level
UNION ALL
SELECT level || '>' FROM chain WHERE length(level) < 5
)
select * from chain
;
+-------+
| level |
+-------+
| A |
| A> |
| A>> |
| A>>> |
| A>>>> |
+-------+
5 row(s) fetched.
Elapsed 0.043 seconds.
```
Also works in my use case.
Thanks!
