如何修改PostgreSQL数据库中所有表的所有者?

我尝试了ALTER TABLE * OWNER TO new_owner,但它不支持星号语法。

Docker:修改所有表和序列的所有者

export user="your_new_owner"
export dbname="your_db_name"

cat <<EOF | docker run -i --rm --link postgres:postgres postgres sh -c "psql -h \$POSTGRES_PORT_5432_TCP_ADDR -p \$POSTGRES_PORT_5432_TCP_PORT -U postgres -d $dbname" | grep ALTER | docker run -i --rm --link postgres:postgres postgres sh -c "psql -h \$POSTGRES_PORT_5432_TCP_ADDR -p \$POSTGRES_PORT_5432_TCP_PORT -U postgres -d $dbname"
SELECT 'ALTER TABLE '||schemaname||'.'||tablename||' OWNER TO $user;' FROM pg_tables WHERE schemaname = 'public';
SELECT 'ALTER SEQUENCE '||relname||' OWNER TO $user;' FROM pg_class WHERE relkind = 'S';
EOF

其他回答

在PostgreSQL中没有这样的命令。但是您可以使用我之前为GRANTs描述的方法来解决它。

下面这个更简单的shell脚本适合我。

#!/bin/bash
for i in  `psql -U $1  -qt -c  "select tablename from pg_tables where schemaname='$2'"`
do
psql -U $1 -c  "alter table $2.$i set schema $3"
done

其中输入$1 -用户名(数据库) $2 =现有模式 $3 =新模式。

ansible非常简单。你也可以跳过obj_type来修改任何对象类型的所有权。

- name: Reassigner owner of all objects
  postgresql_owner:
    login_user: "{{ postgres_admin_username }}"
    login_unix_socket: "{{postgres_socket}}"
    db: "db-name"
    new_owner: "new-owner"
    reassign_owned_by: "old-owner"
    obj_type: "table"

以下是带有进一步信息的文档:https://docs.ansible.com/ansible/latest/collections/community/general/postgresql_owner_module.html

希望这能有所帮助。

可以使用REASSIGN OWNED命令。

剧情简介:

重新分配old_role[,…]到new_role

这将把old_role拥有的所有对象更改为新角色。你不需要考虑用户拥有什么样的对象,它们都会被改变。注意,它只应用于单个数据库中的对象。它也不会改变数据库本身的所有者。

它至少可以在8.2版本中使用。他们的网上资料只能追溯到这段时间。

我喜欢这个,因为它可以一次性(在一个sql语句中)修改某个模式的表、视图、序列和函数所有者,而不需要创建函数,你可以直接在PgAdmin III和psql中使用它:

(在PostgreSql v9.2中测试)

DO $$DECLARE r record;
DECLARE
    v_schema varchar := 'public';
    v_new_owner varchar := '<NEW_OWNER>';
BEGIN
    FOR r IN 
        select 'ALTER TABLE "' || table_schema || '"."' || table_name || '" OWNER TO ' || v_new_owner || ';' as a from information_schema.tables where table_schema = v_schema
        union all
        select 'ALTER TABLE "' || sequence_schema || '"."' || sequence_name || '" OWNER TO ' || v_new_owner || ';' as a from information_schema.sequences where sequence_schema = v_schema
        union all
        select 'ALTER TABLE "' || table_schema || '"."' || table_name || '" OWNER TO ' || v_new_owner || ';' as a from information_schema.views where table_schema = v_schema
        union all
        select 'ALTER FUNCTION "'||nsp.nspname||'"."'||p.proname||'"('||pg_get_function_identity_arguments(p.oid)||') OWNER TO ' || v_new_owner || ';' as a from pg_proc p join pg_namespace nsp ON p.pronamespace = nsp.oid where nsp.nspname = v_schema
    LOOP
        EXECUTE r.a;
    END LOOP;
END$$;

更好的方法是:更改数据库和模式所有者。

DO $$DECLARE r record;
DECLARE
    v_schema varchar := 'public';
    v_new_owner varchar := 'admin_ctes';
BEGIN
    FOR r IN 
        select 'ALTER TABLE "' || table_schema || '"."' || table_name || '" OWNER TO ' || v_new_owner || ';' as a from information_schema.tables where table_schema = v_schema
        union all
        select 'ALTER TABLE "' || sequence_schema || '"."' || sequence_name || '" OWNER TO ' || v_new_owner || ';' as a from information_schema.sequences where sequence_schema = v_schema
        union all
        select 'ALTER TABLE "' || table_schema || '"."' || table_name || '" OWNER TO ' || v_new_owner || ';' as a from information_schema.views where table_schema = v_schema
        union all
        select 'ALTER FUNCTION "'||nsp.nspname||'"."'||p.proname||'"('||pg_get_function_identity_arguments(p.oid)||') OWNER TO ' || v_new_owner || ';' as a from pg_proc p join pg_namespace nsp ON p.pronamespace = nsp.oid where nsp.nspname = v_schema
        union all
        select 'ALTER SCHEMA "' || v_schema || '" OWNER TO ' || v_new_owner 
        union all
        select 'ALTER DATABASE "' || current_database() || '" OWNER TO ' || v_new_owner 
    LOOP
        EXECUTE r.a;
    END LOOP;
END$$;
