greenplum下schema的使用

新建角色python：可以登陸，繼承權限
CREATE role python WITH LOGIN ENCRYPTED PASSWORD '111111';
新建模式temp,給python用戶存放臨時表
CREATE SCHEMA temp;
grant all on schema temp to python;
grant create on schema temp to python;
grant usage on schema temp to python;
將gpadmin創建的表，授權給python
grant select on glfmwdkz to python;

python用戶登陸后使用表(public模式下只讀，temp可以讀寫):
create table temp.g1(like glfmwdkz);
insert into temp.g1 select * from glfmwdkz;
