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.
try
        {
            if (!processQueryText(input))
                break;
        }
        catch (const Exception & e)
        {
            /// We don't need to handle the test hints in the interactive mode.
            std::cerr << "Exception on client:" << std::endl << getExceptionMessage(e, print_stack_trace, true) << std::endl << std::endl;
            client_exception.reset(e.clone());
        }
        if (client_exception)
        {
            /// client_exception may have been set above or elsewhere.
            /// Client-side exception during query execution can result in the loss of
            /// sync in the connection protocol.
             allow to enter the next query.
            if (!connection->checkConnected(connection_parameters.timeouts))
                connect();
        }
    }
    while (true);
    if (isNewYearMode())
        std::cout << "Happy new year." << std::endl;
    else if (isChineseNewYearMode(local_tz))
        std::cout << "Happy Chinese new year. 春节快乐!" << std::endl;
    else
        std::cout << "Bye." << std::endl;
}
