Postgres創建管理員角色

--創建角色，賦予角色屬性
create user batman password '12345' superuser createrole createdb
--添加到角色組
grant postgres to batman 

以上是直接創建管理員角色，如果是修改一個角色為管理員角色的話

alter role spiderman createrole;

創建用戶的格式為：

CREATE ROLE name [ [ WITH ] option [ ... ] ]

where option can be:

      SUPERUSER | NOSUPERUSER
    | CREATEDB | NOCREATEDB
    | CREATEROLE | NOCREATEROLE
    | INHERIT | NOINHERIT
    | LOGIN | NOLOGIN
    | REPLICATION | NOREPLICATION
    | BYPASSRLS | NOBYPASSRLS
    | CONNECTION LIMIT connlimit
    | [ ENCRYPTED | UNENCRYPTED ] PASSWORD 'password'
    | VALID UNTIL 'timestamp'
    | IN ROLE role_name [, ...]
    | IN GROUP role_name [, ...]
    | ROLE role_name [, ...]
    | ADMIN role_name [, ...]
    | USER role_name [, ...]
    | SYSID uid

 

數據庫的一些設置：

1、最大連接數設置 max_connections = 1000
2、轉義打開 standard_conforming_strings = off
