我在CentOS服务器上安装了PostgreSQL 8.4,并从shell连接到root用户并访问PostgreSQL shell。
我在PostgreSQL中创建了数据库和用户。
尝试从我的PHP脚本连接时,它显示身份验证失败。
如何创建新用户以及如何为特定数据库授予权限?

从CLI:
$ su - postgres
$ psql template1
template1=# CREATE USER tester WITH PASSWORD 'test_password';
template1=# GRANT ALL PRIVILEGES ON DATABASE "test_database" to tester;
template1=# \q
PHP(在localhost上测试,它按预期工作):
$connString = 'port=5432 dbname=test_database user=tester password=test_password';
$connHandler = pg_connect($connString);
echo 'Connected to '.pg_dbname($connHandler);

使用密码创建用户:
http://www.postgresql.org/docs/current/static/sql-createuser.html
CREATE USER name [ [ WITH ] option [ ... ] ]
where option can be:
SUPERUSER | NOSUPERUSER
| CREATEDB | NOCREATEDB
| CREATEROLE | NOCREATEROLE
| CREATEUSER | NOCREATEUSER
| INHERIT | NOINHERIT
| LOGIN | NOLOGIN
| REPLICATION | NOREPLICATION
| CONNECTION LIMIT connlimit
| [ ENCRYPTED | UNENCRYPTED ] PASSWORD 'password'
| VALID UNTIL 'timestamp'
| IN ROLE role_name [, ...]
| IN GROUP role_name [, ...]
| ROLE role_name [, ...]
| ADMIN role_name [, ...]
| USER role_name [, ...]
| SYSID uid
然后授予特定数据库的用户权限:
http://www.postgresql.org/docs/current/static/sql-grant.html
示例:
grant all privileges on database db_name to someuser;
