远程连接postgresql问题.连接不上.
连线被拒，请检查主机名称和埠号，并确定 postmaster 可以接受 TCP/IP 连线
postgres远程连接失败：
在本机上连接都没有问题，代码如下：
  String strUrl = "jdbc:postgresql://127.0.0.1:5432/postgres";
  String strDriver = "org.postgresql.Driver";
  String user = "postgres";
  String password = "1234";
  try {
  Class.forName(strDriver);
  conn = DriverManager.getConnection(strUrl, user, password);
  stmt = conn.createStatement();
  } catch (Exception e) {
  System.err.println("open postgresdb failed!");
  }
远程连接，就失败：
String postSQLUrl = "jdbc:postgresql://10.100.112.131:5432/postgres";
  String postSQLDriver = "org.postgresql.Driver";
  String strUser = "postgres";
  String strPassword = "1234";
  try {
  Class.forName(postSQLDriver).newInstance();
  conn = DriverManager.getConnection(postSQLUrl,strUser, strPassword);
  stmt = conn.createStatement();
  } catch (Exception e) {
  e.printStackTrace();
  System.err.println("open postgreSQL db failed!");
  }
