3 ，以下是配置用户，环境变量，乱七八糟后就会成功

[[e-mail] ~]# cp .bash_profile .bashrc /home/PostgreSQL/8.4/
cp: overwrite `/home/PostgreSQL/8.4/.bash_profile’? y
cp: overwrite `/home/PostgreSQL/8.4/.bashrc’? y
[[e-mail] ~]# chown -R postgres.postgres /home/PostgreSQL/*
[[e-mail] ~]# ls -ltr /home/PostgreSQL/8.4/.bash*
-rw-r–r– 1 postgres postgres 174 Nov 10 19:18 /home/PostgreSQL/8.4/.bash_profile
-rw-r–r– 1 postgres postgres 176 Nov 10 19:18 /home/PostgreSQL/8.4/.bashrc
[[e-mail] ~]# su – postgres

4, 初始化数据库完毕，类似于MySQL的installdb

[[e-mail] data]$ initdb -D /home/PostgreSQL/8.4/data/
The files belonging to this database system will be owned by user "postgres".
This user must also own the server process.
The database cluster will be initialized with locale en_US.
The default database encoding has accordingly been set to LATIN1.
The default text search configuration will be set to "english".

WARNING: enabling "trust" authentication for local connections
You can change this by editing pg_hba.conf or using the -A option the
next time you run initdb.
Success. You can now start the database server using:
postgres -D /home/PostgreSQL/8.4/data
or
pg_ctl -D /home/PostgreSQL/8.4/data -l logfile start
[[e-mail] data]$

5, 启动PostgreSQL Server 后台服务

[[e-mail] data]$ pg_ctl -D /home/PostgreSQL/8.4/data -l logfile start
server starting
[[e-mail] data]$

二，使用方法

[[e-mail] data]$ psql
psql (8.4.1)
Type "help" for help.
postgres=#
[[e-mail] bin]$ ./createdb imdba
[[e-mail] bin]$ psql imdba
psql (8.4.1)
Type "help" for help.
imdba=# \l

template1 | postgres | LATIN1   | en_US     | en_US | =c/postgres  : postgres=CTc/postgres
(4 rows)
imdba=#
imdba=# \c postgres
psql (8.4.1)
You are now connected to database "postgres".
postgres=# \c imdba
psql (8.4.1)
You are now connected to database "imdba".
imdba=# create table imdba(id int4,name char(16));
CREATE TABLE
imdba=# drop table imdba;
DROP TABLE
imdba=# create table t_imdba(id int4,name char(16));
CREATE TABLE
imdba=# \d t_imdba
       Table "public.t_imdba"
Column |     Type      | Modifiers

1 ，备份数据库

[@tc_10.11.54.21_cnc bin]$ pg_dump
pg_dump     pg_dumpall
[[e-mail] bin]$ pg_dump imdba >imdba.pgsql
[[e-mail] bin]$ more imdba.pgsql
–
– PostgreSQL database dump
–
SET statement_timeout = 0;
SET client_encoding = ‘LATIN1′;
SET standard_conforming_strings = off;
SET check_function_bodies = false;
SET client_min_messages = warning;
SET escape_string_warning = off;
SET search_path = public, pg_catalog;
SET default_tablespace = ”;

REVOKE ALL ON SCHEMA public FROM PUBLIC;
REVOKE ALL ON SCHEMA public FROM postgres;

2 ，恢复数据库

[[e-mail] bin]$ dropdb  imdba
[[e-mail] bin]$ psql imdba < imdba.pgsql
[[e-mail] bin]$ ./createdb imdba
[[e-mail] bin]$ psql imdba < imdba.pgsql
