extern crate "iron-postgres-middleware" as pg_middleware;
use pg_middleware::{PostgresMiddleware, PostgresReqExt};

Using middleware

fn main() {
  let mut router = Router::new();
  router.get("/", handler);

  let mut c = ChainBuilder::new(router);

  let pg_middleware = PostgresMiddleware::new("postgres://user@localhost/db_name");
  c.link_before(pg_middleware);

  Iron::new(c).listen(SocketAddr { ip: Ipv4Addr(127, 0, 0, 1), port: 3000 }).unwrap();
}

fn handler(req: &mut Request) -> IronResult<Response> {

  con.execute("INSERT INTO foo (bar) VALUES ($1)", &[&1i32]).unwrap();
  Ok(Response::new().set(status::Ok).set("Success"))
