如何查看postgresql用户权限

1、查看某用户的表权限

select * from information_schema.table_privileges where grantee='user_name';

2、查看usage权限表

select * from information_schema.usage_privileges where grantee='user_name';

3、查看存储过程函数相关权限表

select * from information_schema.routine_privileges where grantee='user_name';

4、建用户授权

create user user_name;
alter user user_name with password '';
alter user user_name with CONNECTION LIMIT  20;#连接数限制
