I still like having poll() on both the connection and the cursor, 
because internally they are doing different things.

connection.poll() is issuing PQconnectPoll (and taking care issuing some 
initial queries) and cursor.poll() is issuing PQconsumeInput and 
PQflush. The idea is that you initiate some async action (like 
connecting or executing) and then you poll until that action is complete 
(if you're connecting you poll the connection, if executing you poll the 
cursor).
