```java

import com.nebhale.bindings.Binding;

import com.nebhale.bindings.Bindings;

import java.sql.Connection;

import java.sql.DriverManager;

import java.sql.SQLException;

public class Application {

    public static void main(String[] args) {

        Binding[] bindings = Bindings.fromServiceBindingRoot();

        bindings = Bindings.filter(bindings, "postgresql");

        if (bindings.length != 1) {

            System.err.printf("Incorrect number of PostgreSQL drivers: %d\n", bindings.length);

            System.exit(1);

        }

        String url = bindings[0].get("url");

        if (url == null) {

            System.err.println("No URL in binding");

            System.exit(1);

        }

        Connection conn;

        try {

            conn = DriverManager.getConnection(url);

        } catch (SQLException e) {

            System.err.printf("Unable to connect to database: %s", e);

            System.exit(1);
