title: SQLAlchemy, Psycopg2 and Postgresql COPY
body: <p>It looks like Psycopg has a custom command for executing a <a href="http://www.postgresql.org/docs/current/static/sql-copy.html" rel="noreferrer">COPY</a>:</p>
  
  <p><a href="https://stackoverflow.com/questions/3491864/">psycopg2 COPY using cursor.copy_from() freezes with large inputs</a></p>
  
  <p>Is there a way to access this functionality from with SQLAlchemy?</p>
