   One thing I've noticed is that the async queries seem to be incompatible with the query iterators and indexing.

   Compare

   $ python3 -c "import pg; db=pg.DB(); ret=db.send_query('SELECT 1; SELECT 2;'); print(ret[0]); print(ret[0]); print(ret[0]);"i in ret]); print([i for i in ret])
   (1,)
   (2,)
   None
   
   $ python3 -c "import pg; db=pg.DB(); ret=db.query('SELECT 1; SELECT 2;'); print(ret[0]); print(ret[0]); print(ret[0]);"ret]); print([i for i in ret])
   (2,)
   (2,)
   (2,)
   

   That's an unfortunate limitation, and inconsistency.
