title: Load a large DataFrame from Pandas to Postgresql
body: <p>I have been trying to load a huge DF into postgres table with <code>SqlAlchemy</code> but the process is always been killed after a while.
  Is there a better way to do this with pandas? </p>
  
  <pre><code>...
  
  &gt;&gt;engine = create_engine('postgresql://stargateuser:5tar9ate@localhost/stargate',encoding='utf-8', echo=True)
  
  &gt;&gt;MainName.to_sql("landingpage_mainname", con=engine, if_exists="replace")
  Killed
  </code></pre>
