Re: Updateable cursors patch

No. It works with scrollable cursors. It will work for cursors/selects
which does not put the results in some store, such as WITH hold/group
by/order by etc.... But most of these restrictions apply for normal
'Select for update' anyway. (With the order by clause, the
implementation is as per the sql standards.)

I can update the documentation once the initial review is done and what
I have done gets atleast a pass mark :-)
