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.
