Table schema

select

SUM(SALDO_EUR)
from
Table

Problem description

1. Expected behaviour:
   When we use functions such as sum() the query result should display the exact column name like we have defined in the SQL-Query
2. Actual behaviour:
   When we use functions such as sum() the query result is missing the column name within the functions brackets
3. Error message/stack trace:
   No error message for this issue.
4. Any other details that can be helpful:

Result:

('gs_pe', 1043, None, None, None, None, None)
('sc_pe', 1043, None, None, None, None, None)
('sum', 1700, None, None, None, None, None)

Expected Result:

('gs_pe', 1043, None, None, None, None, None)
('sc_pe', 1043, None, None, None, None, None)
('sum(saldo_euro)', 1700, None, None, None, None, None)

Sorry, I have no privileges to create tables on the Redshift DB.

Reproduction code

with conn.cursor() as cur:
    cur.execute(sql)
    tuples_list = cur.fetchall()
    dataframe = pd.DataFrame(tuples_list, columns=[desc[0] for desc in cur.description], dtype="object")
    for field in cur.description:
        print(field)
