Not to be created directly from its constructor, the Query is returned from Client#connect. It functions primarily as an EventEmitter allowing you to handle returned rows.

• events
  • row
  • end

I'm still working on the API for prepared statements. Check out the tests for more up to date examples, but what I'm working towards is something like this:

 var client = new Client({
   user: 'brian',
   database: 'test'
 });

 var query = client.query({
   text: 'select * from person where age < $1',
   values: [21]
 });

 query.on('row', function(row) {
   console.log(row);
 });

 query.on('end', function() { client.end() });
