命令
下面列出的是一些我们经常要用到的命令，当然还有很多其它的命令，更详细的信息可以查看man帮助页或其它文档。
在"pg_hba.conf"文件的PG_DATA段可以用ip地址和用户名限制对能数据库的连接。
l 用“createuser”命令在数据库中定义一个新用户：
[root@deep]# su postgres
[postgres@deep]$ createuser
Enter name of user to add ---> admin
Enter user's postgres ID or RETURN to use unix user ID: 500 ->
Is user "admin" allowed to create databases (y/n) y
Is user "admin" a superuser? (y/n) y
createuser: admin was successfully added
l 用“destroyuser”命令在数据库中删除用户：
[root@deep]# su postgres
[postgres@deep]$ destroyuser
Enter name of user to delete ---> admin
destroyuser: delete of user admin was successful.
l 用“createdb”命令创建新的数据库：
[root@deep]# su postgres
[postgres@deep]$ createdb dbname (the name of the database).
也可以用postgres的终端程序（psql）完成：
[root@deep]# su admin
[admin@deep]$ psql template1
Welcome to the POSTGRESQL interactive sql monitor:

type ? for help on slash commands
type q to quit
type g or terminate with semicolon to execute query
You are currently connected to the database: template1
template1 è create database foo;
CREATEDB
其它一些有用的终端程序（psql）命令：
l 连接到另外的数据库：
template1 è c foo
connecting to new database: foo
foo è
l 创建一个表：
foo è create table bar (i int4, c char(16));
CREATE
foo è
l 检查新表：
foo è d bar
Table = bar
+-------+--------+--------+
| Field | Type | Length |
+-------+--------+--------+
| I | int4 | 4 |
| c | char() | 16 |
+-------+--------+--------+
foo è
l 删除表、索引、视图：
foo è drop table table_name;
foo è drop index index_name;
foo è drop view view_name;
l 往一个表里插入记录：
foo è insert into table_name (name_of_attr1, name_of_attr2, name_of_attr3)
foo è values (value1, value2, value3);
