CaselIT opened a new issue, #3543:
URL: https://github.com/apache/arrow-adbc/issues/3543
### What happened?
If I access `cursor.description` before calling fetch_arrow or fetch_polars
an exception is raised:
> ProgrammingError: Result set has been closed or consumed
Using `fetch_arrow_table` or `fetch_df` works instead
### Stack Trace
```
Traceback (most recent call last):
File "source,py", line 77, in <module>
print(cur.fetch_polars())

```
### How can we reproduce the bug?
# any driver will do the same, example postgres
```py
from adbc_driver_postgresql.dbapi import connect
url = 'postgresql://scott:tiger@localhost/test'
c = connect(url)
with c:
with c.cursor() as cur:
cur.execute('select 42 as col')
print(cur.description) # commenting this like makes it work
print(cur.fetch_polars())
```
### Environment/Setup
adbc_driver_manager = 1.8.0
adbc_driver_postgresql = 1.8.0
