How do I use node-postgres in a server?

Question

I\'m writing a Node.js web server that uses a Postgres database. I used to connect on each new request like this:

app.get(\'/\', function (req, res) {
  pg.conne

I'm assuming you're using the latest version of node-postgres, in which the connection pooling has been greatly improved. You must now check the connection back into the pool, or you'll bleed the connections:

app.get('/', function (req, res) {
  pg.connect(pgconnstring, function (err, client, done) {
    // do some stuff
    done();
  });
});

As for error handling on a global connection (#2, but I'd use the pool):

client.on('error', function(e){
  client.connect(); // would check the error, etc in a production app
});

The "missing" docs for all this is on the GitHub wiki.
