Access the database after disconnecting

Access the database after disconnecting
I can able to execute queries on a ClickHouse database after disconnecting the client without encountering a NetworkError as expected.

To Reproduce

Modules

from clickhouse_driver import Client
from clickhouse_driver.errors import NetworkError

Create a ClickHouse client

client = Client(
host=host,
port=9000,
database='ClickHouse_DB'
user='default',
password='pass',
)

try:
# Execute the first query
response = client.execute("describe table_name")
print(response)
except NetworkError as e:
print(f"Error: {e}")
print("The client encountered a NetworkError.")

Disconnect the ClickHouse client

client.disconnect()

try:
# Attempt to execute a query after disconnecting (this will likely raise a NetworkError)
response = client.execute("describe table_name")
print(response)
except NetworkError as e:
print(f"Error: {e}")
print("The client encountered a NetworkError after disconnecting.")

Expected behavior
NetworkError excepted.
