Hello Tom, >> This is one of the patches already marked as RFC (since September by >> Alvaro).

(The thread title is completely misleading > about that; there's no "option" in the patch as it stands.) The thread title was not misleading, the initial version of the patch did offer an option. Then I was said "the current behavior is stupid (which I agree), let us change it to the sane behavior without option", then I'm told the contrary. Sigh. I still have the patch with the option, though. > Sure, in a green field this behavior would likely be more sensible ... > but that has to be weighed against the fact that it's behaved the way it > does for a long time, and any existing scripts that are affected by that > behavior have presumably deliberately chosen to use it.

Why would there be bug report if this is a feature? :-) The behavior has been irritating me for a long time. It is plain stupid to be able to send queries but not see their results. -- Fabien.
