Recovering a dropped table in PostgreSQL

I have :

CREATE TABLE ketoan_vn.Customers
(
  CustomerId character varying(10) NOT NULL,
  CustomerName character varying(150),
  CONSTRAINT Customers_PK_CustomerID PRIMARY KEY (CustomerId)
);

I inserted 2 rows into table ketoan_vn.Customers:

INSERT INTO ketoan_vn.customers(
            customerid, customername)
    VALUES ('C0001','Marry'),
    ('C0002','Tom');

I then dropped ketoan_vn.Customers :

drop table ketoan_vn.Customers

Now I want to recover the data of the dropped table. Is this possible with PostgreSQL 9.1?
