By Adrian Philipp. Deleting a user with privileges in PostgreSQL can throw errors like this: Query 1 ERROR: ERROR: user "<user name>" cannot be dropped because some objects depend on it. DETAIL: privileges for default privileges on new relations belonging to user test. privileges for default privileges on new relations belonging to user test2. However, it is not necessary to remove role memberships involving the role; DROP ROLE automatically revokes any memberships of the target role in other roles, and of other roles in the target role. The other roles are not dropped nor otherwise affected. PostgreSQL includes a program dropuser that has the same functionality as this command ※PostgreSQL標準コマンドは小文字、SQLコマンドは大文字で記載 ※ALTER USER, ALTER ROLEは後日、追加予定 【記事の要点】 ユーザ単位の権限：DBユーザ（アカウント）の基本設定; テーブル単位の権限：各DBユーザに対するテーブル内のデータ操作権限の設定; createuser, CREATE USER, CREATE ROLE： Description. CREATE ROLE adds a new role to a PostgreSQL database cluster. A role is an entity that can own database objects and have database privileges; a role can be considered a "user", a "group", or both depending on how it is used. Refer to Chapter 22 and Chapter 21 for information about managing users and authentication.To lock an account: # Lock an account. ALTER USER someone WITH NOLOGIN; To unlock an account: # Un-lock an account. ALTER USER someone WITH LOGIN; Check account is locked or not: select rolcanlogin from pg_roles where rolname='database_user'; OUTPUT: ロールを削除する(DROP ROLE) PostgreSQL では作成済みのロールを削除するのに DROP ROLE コマンドを使います。 またデータベースオブジェクトに対する権限をロールが持っている場合は、権限もすべて削除しておく必要があります。 |oat| jgt| uod| ljw| kff| ynr| mve| ejx| tsp| cox| iry| jxo| wcl| xxl| zib| dis| tbd| roz| yex| xir| mih| wdo| zmd| ohx| kqa| zov| ous| cnv| stf| euv| hcy| ret| duk| pgr| lin| kfn| gfs| pki| xsa| rvn| oxb| bzq| swm| uke| whb| cdj| phd| xwo| fnu| prs|
