raw_query tests fail with psycopg1 backend

[Karen Tracey]

Failure is:

FAILED (errors=1)

(Thhis was with --failfast specified so tests stopped after first failure.)

Just for the record, the psycopg cursor does not implement any 'dunder' (double-underscore) methods...

>>> import psycopg, psycopg2
>>>
>>> conn1=psycopg.connect("user=username password=pwd")
>>> conn2=psycopg2.connect("user=username password=pwd")
 
>>> cur1=conn1.cursor()
>>> iter(cur1)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: 'cursor' object is not iterable
 
>>> cur2=conn2.cursor()
>>> iter(cur2)

(In [12845]) Fixed #12759 -- Fixed the iterator method on psycopg1 cursors, which was preventing the raw_query tests from passing.
