### Simple
Sometimes you may not want to use a pool of connections. You can easily connect a single client to a postgres instance, run a query, and disconnect.
```javascript
var pg = require('pg');
//or native libpq bindings
//var pg = require('pg').native
var conString = "postgres://postgres:1234@localhost/postgres";
var client = new pg.Client(conString);
client.connect(function(err) {

console.log(result.rows[0].theTime);
