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.

    if (!block)
        return;
    proc= block.rows();
    /// Even if all blocks are empty, we still need to initialize the output stream to write empty resultset.
    initOutputFormat(block, parsed_query);
    /// The header block containing zero rows was used to initialize
    /// output_format, do not output it.
     data if we're fuzzing.
    if (block.rows() == 0 || (query_fuzzer_runs != 0 && processed_rows >= 100))
        return;
    /// If results are written INTO OUTFILE, we can avoid clearing progress to avoid flicker.
    if (need_render_progress && (stdout_is_a_tty || is_interactive) && (!select_into_file || select_into_file_and_stdout))

    }
