title: psycopg2.extras.execute_values to insert multiple rows for geometry data
body: <p>This is my insert query</p>
  
  <pre><code>sql = "INSERT INTO sightings (run_id, geometry, properties)
               VALUES(%s, ST_MakePoint(%s, %s), %s);"
  </code></pre>
  
  <p>1) run_id is an internal uuid</p>
  
  <p>2) geometry - this is geopoint object</p>
  
  <p>3) properties is a JSON object</p>
  
  <p>On running <code>psycopg2.extras.execute_values(cur, sql, listOfTuples)</code> I get an error that says:</p>
  
  <blockquote>
    <p>the query contains more than one '%s' placeholder'</p>
  </blockquote>
  
  <p>I realize my mistake around this, but how can I get around it. Is there a way the template parameter can be of any help.</p>
