1、创建test10_tbs的表空间，在这个表空间中创建数据库testdb10
create tablespace test10_tbs relative location 'tablespace/test10_tbs';
create database testdb10 with tablespace test10_tbs;
omm=# create tablespace test10_tbs relative location 'tablespace/test10_tbs';
create database testdb10 with tablespace test10_tbs;CREATE TABLESPACE
omm=# create database testdb10 with tablespace test10_tbs;
CREATE DATABASE
omm=# \l

2、使用create user创建用户user10，登录数据库testdb10，创建测试表t1和t2
create user user10 identified by 'qaz_hc123';
grant all privileges on database testdb10 to user10;
\quit
gsql -Uuser10 -Wqaz_hc123 -r -d testdb10
create table t1 as select * from pg_class;
create table t2 as select * from pg_class;
omm=# create user user10 identified by 'qaz_hc123';
CREATE ROLE
omm=# grant all privileges on testdb10 to user10;
ERROR: relation "testdb10" does not exist
omm=# grant all privileges on database testdb10 to user10;
GRANT
omm=# gsql -Uuser10 -Wqaz_hc123 -r -d testdb10
omm-# \quit
omm@911d320f8566:~$ gsql -Uuser10 -Wqaz_hc123 -r -d testdb10

create role role10 identified by 'qaz_hc123';

gsql -Urole10 -Wqaz_hc123 -r -d testdb10;
