New description:
psycopg2.extras.!DictCursor doesn't implement !__iter!__, so iterating a
!DictCursor doesn't assign the index variables thus leaving an incomplete
!DictCursor.
I wrote this simple !__iter!__ function:
{{{
def __iter__(self):
while True:
row = self.fetchone()
if not row:
break
yield row
}}}
Comment:
After a little investigation: !DictCursor does not need to implement
!__iter!__ because the !__iter!__ in the base cursor returns itself (as it
should be). The error was the missing next() method in !DictCursor. This
was fixed some time ago.
