装载/访问数据库：

sudo -u postgres psql     ## or: sudo su postgres

postgres=# \i northwind.postgre.sql;

postgres=# \d
                List of relations

(15 rows)

postgres=# \d customers;
             Table "public.customers"
    Column    |         Type          | Modifiers 
--------------+-----------------------+-----------
 CustomerID   | bpchar                | not null
 CompanyName  | character varying(40) | not null
 ContactName  | character varying(30) | 
 ContactTitle | character varying(30) | 
 Address      | character varying(60) | 
 City         | character varying(15) |

 Phone        | character varying(24) | 
 Fax          | character varying(24) | 
Indexes:
    "pk_customers" PRIMARY KEY, btree ("CustomerID")

# Note the following query error:

postgres=# SELECT DISTINCT City FROM customers ORDER BY City;
ERROR:  column "city" does not exist
LINE 1: SELECT DISTINCT City FROM customers ORDER BY City;
                        ^

# ... use use double-quotes if your column name
# (etc.) contains some uppercase characters:

postgres=# SELECT DISTINCT "City" FROM customers ORDER BY "City";
      City

此数据库以这种优良使用（例如），在线教程（I跳过前面几页到第一页提到它）：

在其它两个答案似乎是过时的。

您可以从这个链接得到的Northwind数据库创建脚本

使用PG的管理员或psql的指令Run查询

如果你真的想要那个特定一个，你可以抓住罗斯文从单位的DBLinq测试数据集的PostgreSQL的端口。请参见 http://groups.google.com/group/dblinq/web/unit -tests 关于如何做到这一点比较粗略的笔记。
