PostgreSQL是支持“區域”，“字符集支持”的，允許你使用本區域的字符集做為欄位名。但要注意，你的終端要支持該字符集支持。我這裡使用UNICODE，EUC_CN也適用。

Create table "組"(
       "序號" Serial NOT NULL UNIQUE,
       "組名" Varchar(20) NOT NULL,
       "描述" Varchar(255),
       UNIQUE ("組名"),
      PRIMARY KEY ("序號")
);

創建表：
member=> Create table "組"(
member(> "序號" Serial NOT NULL UNIQUE,
member(> "組名" Varchar(20) NOT NULL,
member(> "描述" Varchar(255),
member(> UNIQUE ("組名"),
member(>  PRIMARY KEY ("序號")
member(> );
NOTICE:  CREATE TABLE will create implicit sequence '組_序號_seq' for SERIAL column '組.序號'
NOTICE:  CREATE TABLE / PRIMARY KEY will create implicit index '組_pkey' for table '組'
NOTICE:  CREATE TABLE / UNIQUE will create implicit index '組_組名_key' for table '組'
CREATE TABLE

查看表結構：

member=> \d 組
                                     Table "public.組"
 Column |          Type          |                         Modifiers
--------+------------------------+-----------------------------------------------------------
 序號 | integer                | not null default nextval('public."組_序號_seq"'::text)
 組名 | character varying(20)  | not null
 描述 | character varying(255) |
Indexes: 組_pkey primary key btree ("序號"),
         組_組名_key unique btree ("組名")

插入數據：
member=> insert into 組(組名,描述) values('域用戶','9812.net域內用戶');
INSERT 110971 1
member=> insert into "組"("組名","描述") values('域用戶','9812.net域內用戶');
ERROR:  Cannot insert a duplicate key into unique index 組_組名_key
member=> insert into "組"("組名","描述") values('計算機維護組','維護計算機的用戶用戶');
INSERT 110973 1

查看數據：
member=> select * from 組;
 序號 |       組名       |             描述
--------+--------------------+--------------------------------
      1 | 域用戶          | 9812.net域內用戶

註：在操作非英文欄位的表時。建議最好前，後加上“"”，“"”符號。並非所有API都支持非英文的編碼。
