nuno-faria opened a new issue, #25545:
URL: https://github.com/apache/datafusion/issues/25545
### Describe the bug
When unparsing a plan with a `SubqueryAlias` + `FilterExec`, the resulting
SQL can be invalid, since the alias will be applied to the base table while the
filter still refers to the previous table name.
### To Reproduce
This query
```sql
select *
from (
select a
from t
) t2
where a = 1
```
is optimized to a plan like this
```sql
SubqueryAlias: t2
Filter: t.a = Int32(1)
TableScan: t projection=[a]
```
which is unparsed to
```sql
SELECT * FROM t AS t2 WHERE (t.a = 1) -- t.a is invalid
```
