title: psql.frame_query
body: <p>Does anyone have a link to a description of all the possible inputs into psql.frame_query() for pandas?</p>
  
  <p>I have a situation where I have a number of parameters psql.execute(string, con, params).  There doesn't seem to be a similar option in psql.frame_query.  Any recommendations?</p>
  
  <p>Thanks.</p>
