title: Lightweight DBAL for python
body: <p>can somebody please recomend me some python DBAL library that will best suit my requirements. I would like to write my sql statements directly, most of the logics will be in db stored procedures (postgresql), so I only need to invoke db procedures, pass arguments to them and fetch the results. The library should help me with quoting (preventing sql inject). 
  I played with sqlalchemy, but i think that there is no quoting helper when writing sql statement directly to engine.execute method.</p>
  
  <p>Thank you</p>
