一、配置说明:
角色名称:user01
1.user01权限说明:
在指定schema,建立\查看\删除表,查看schema中对象;
2.其它普通用户:
无法连接test数据库及schema(sales)中对象,需要授权;
二、操作步骤:
instance(实例级): role(角色)
$ psql postgres
postgres=# CREATE ROLE user01 LOGIN NOSUPERUSER NOCREATEDB;
2.database(数据库级): CREATE(schemas) and CONNECT(database)
$ psql postgres
postgres=# CREATE DATABASE test;
postgres=# REVOKE ALL ON DATABASE test FROM public; -- 禁止其它普通role连接test
postgres=# GRANT CONNECT ON DATABASE test TO user01;
3.schema(架构级):
CREATE(put object into schema)
USAGE (allow us to actually look into a schema and see which objects are present).
$psql test
test=# REVOKE ALL ON SCHEMA public FROM public;-- 其它普通role无法连接test
test=# CREATE SCHEMA sales;
CREATE SCHEMA
test=# GRANT CREATE,USAGE ON SCHEMA sales TO user01; -- user01 可以在sales中建立、查看对象
GRANT
test=# \q
$ psql test -U user01
test=> CREATE TABLE sales.t_sales (id int4);
CREATE TABLE
4.table(表级): grant
默认user01创建、drop表和DML表内容
5.column(列级):grant
默认user01创建、drop表和DML列内容
