Oracle cli client (sqlplus) has a neat feature, if you put `/[enter]` in the prompt, it re-executes the last SQL.

```sql
:) select 1;
┌─1─┐
│ 1 │
└───┘

:) /
┌─1─┐
│ 1 │
└───┘
```

currently `<up><enter>` pollutes the screen by the SQL text and can contain SQL script, not a single query. Probably echo should be disabled in this case as well.
<< " timeout is " << receive_timeout.totalSeconds() << " seconds." << std::endl;
                        cancelQuery();
                    }
                }
            }
            /// Poll for changes after a cancellation check, otherwise it never reached
            /// because of progress updates from server.
            if (connection->poll())
                break;
        }
        try
        {
            if (!receiveAndProcessPacket(parsed_query, cancelled))
                break;
        }
        catch (const LocalFormatError &)
        {
            local_format_error = std::current_exception();
            connection->sendCancel();
        }
    }
    if (local_format_error)
        std::rethrow_exception(local_format_error);
    if (cancelled && is_interactive)
        std::cout << "Query was cancelled." << std::endl;
