Postgres資料庫使用者密碼有效期設定
pg_user或pg_shadow中：
列valuntil值為infinity或空值表示使用者密碼永不過期；預設為空
修改使用者密碼過期時間:
alter user user_name with valid until '2018-01-01 08:00:00';
修改使用者密碼永不過期:
alter user user_name with valid until 'infinity';
highgo=# select * from pg_user;
usename | usesysid | usecreatedb | usesuper | usecatupd | userepl | passwd | valuntil | useconfig
---------+----------+-------------+----------+-----------+---------+----------+----------+-----------
highgo | 10 | t | t | t | t | ******** | |
