server side cursors update & delete,

Hi,

The section '39.7.3.3. UPDATE/DELETE WHERE CURRENT OF' of
http://www.postgresql.org/docs/9.2/static/plpgsql-cursors.html
specifies the syntax as:

UPDATE table SET ... WHERE CURRENT OF cursor;
DELETE FROM table WHERE CURRENT OF cursor;

Is there a way to generate these syntax for update & delete ?

Right now, if i get the error that .execute() can't be called more than once !

TIA
