jonahgao opened a new issue, #10914:
URL: https://github.com/apache/datafusion/issues/10914
### Describe the bug
In the following query:
```sql
(with cte as (select 1) select * from cte)
union
(select * from cte)
```
The visibility of the `cte` should be limited to the subquery on the left
side of the UNION.
### To Reproduce
Run the following queries in CLI:
```sh
> create table t as values(100);
0 row(s) fetched.
Elapsed 0.025 seconds.
> (with t as (select 1) select * from t) union (select * from t);
+----------+
| Int64(1) |
+----------+
| 1 |
+----------+
1 row(s) fetched.
Elapsed 0.025 seconds.
```
### Expected behavior
The subquery on the right should not reference the CTE, and the result
should be the same as in PostgreSQL.
```sh
postgres=# create table t as values(100);
SELECT 1
postgres=# (with t as (select 1) select * from t) union (select * from t);
?column?
----------
100
1
(2 rows)
```
