I used to do this with Informix before a DELETE:
> SELECT COUNT(*) FROM ... WHERE ...;
and Informix had that "Are your sure" check in dbaccess too, but after I
did the COUNT(*), the prompt was just annoying.
Also, what interfaces allow you to just press ENTER to send a command?
With psql, you have to terminate it with a semicolon or nothing happens.
I think there is justification for an "Are you sure" only if a single
keystroke sends the command.
