DB.Access: Como Listar Tabelas?

con = DriverManager.getConnection("jdbc:postgresql://localhost/teste_db", "blabla", "blablabla");  
              
              
            DatabaseMetaData db_md = con.getMetaData();  
              
            ResultSet res = db_md.getTables(null, null, null,   
                        new String[] {"TABLE"});  
              
            System.out.println("Tabelas da base teste_db:");  
              
              
            while (res.next())  
            {  
                System.out.println(res.getString(3));  
                  
            }  
              
            con.close();
