Hi,

Then  the  "back" button makes no sense, because the user would like to stay
on the same page and look at what went wrong, rather than going to any other
page.

I think when dealing with foreign keys one can come up with incorrect update
statements. In that case, the error message being displayed using
PMA_ajaxShowMessage() isn't helpful enough as it's just transient.
