1、切换到指定数据库
\c axyh_360p_hunan_mobile_security_manage
2、回收权限
1 revoke connect on database axyh_360p_hunan_mobile_security_manage from public;
3、设置授权后的权限
grant对以及在数据库的表进行授权
alter default 对新建的表进行授权延续
1 alter default privileges for user bd_zhangranran in schema public grant insert,select,update,delete,references,trigger on tables to bd_weidubin; 2 运维人员可能会进行重新导表，所以postgres用户也要进行授权延续操作 3 alter default privileges for user postgres in schema public grant insert,select,update,delete,references,trigger on tables to bd_weidubin;
后期zhangjun用户在publi模式下建的表具有insert,select,update,delete,references,trigger权限。grant是对当时及以前的。alter default是对之后的
4、授予连接权限
1 grant connect on database axyh_360p_hunan_mobile_security_manage to bd_miaoyongchao;
