+Basically a facade on top of the connection to provide a _much_ more
+user friendly, "node style" interface for doing all the lovely things
+you like with PostgreSQL.
+
+Now that I've got the __Connection__ api in place, the bulk and meat of
+the work is being done on the __Client__ to provide the best possible
+API.  Help? Yes please!
+
+    var client = new Client({
+      user: 'brian',
+      database: 'postgres',
+    });
+
+    client.query("create temp table ids(id integer)");
+    client.query("insert into ids(id) values(1)");
+    client.query("insert into ids(id) values(2)");
+    var query = client.query("select * from ids", function(row) {
+      row.fields[0] // <- that equals 1 the first time. 2 the second time.
+    });
+    query.on('end', function() {
