Broken error reporting through Python ADBC

[vogelsgesang]

The following query should report a division by zero:

import adbc_driver_flightsql.dbapi as flight_sql

with flight_sql.connect(uri="grpc://localhost:15432",
                        db_kwargs={"username": "avogelsgesang",
                                   "adbc.flight.sql.rpc.call_header.x-flight-sql-database": "avogelsgesang"
                                   }
                        ) as conn:
   with conn.cursor() as cur:
        cur.execute("SELECT 1/0;")

However, this does not work as expected. Instead cur.execute first hangs for a couple of minutes before then reporting

Traceback (most recent call last):
