一.用户
创建用户使用create user语句,一般使用create user with password 'xxx' XXX 其中最后的XXX是给予的角色权限
postgres=# \h create user@H_502_51@;Command@H_502_51@: CREATE USERDescription define a new database roleSyntaxCREATE USER name @H_502_51@[ WITH @H_502_51@] option @H_502_51@...]where option can be SUPERUSER @H_502_51@| NOSUPERUSER CREATEDB NOCREATEDB CREATEROLE NOCREATEROLE CREATEUSER NOCREATEUSER INHERIT NOINHERIT LOGIN NOLOGIN REPLICATION NOREPLICATION BYPASSRLS NOBYPASSRLS CONNECTION LIMIT connlimit ENCRYPTED UNENCRYPTED PASSWORD 'password' VALID UNTIL 'timestamp' IN ROLE role_name @H_502_51@[,...] IN GROUP role_name ROLE role_name ADMIN role_name USER role_name SYSID uid

用户的权限分为系统权限和对象权限
对象权限使用grant语句来赋予:
