It's really different because on the latter, you have a real question.
On the former, there is no question which makes it difficult to
understand what the OK button will do. What will the OK button do? close
the dialog? VACUUM the table (on the VACUUM hint)? one cannot guess that
without trying. Actually, I expect a user to hit more easily the cancel
button than the OK button. Unfortunately, the Cancel button is always
disabled, so it has no meaning at all.
