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。

当前回答
我最近不得不改变数据库中所有对象的所有权。虽然表、视图、触发器和序列可以很容易地更改,但上述方法对于函数来说失败了,因为签名是函数名的一部分。当然,我有MySQL的背景,不太熟悉Postgres。
然而,pg_dump允许你只转储模式,其中包含ALTER xxx OWNER to yyy;你需要的陈述。下面是我在这个话题上的一点贝壳魔法
pg_dump -s YOUR_DB | grep -i 'owner to' | sed -e 's/OWNER TO .*;/OWNER TO NEW_OWNER;/i' | psqL YOUR_DB
其他回答
虽然下面没有改变所有者,但改变了角色,这是我需要做的,当搜索谷歌时,我结束了这个问题,所以为了完整性起见,我将在这里输入:
对我来说,上述解决方案都不起作用,我一直得到:必须是关系xxx的所有者。最终的解决方案是:

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
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。
我为此创建了一个方便的脚本;pg_change_db_owner.sh。此脚本更改数据库模式中所有表、视图、序列和函数的所有权,以及模式本身的所有者。
请注意,如果你只是想改变一个特定数据库中所有对象的所有权, ,那么您可以简单地使用REASSIGN owned命令来代替。
如果当前所有者不是postgres,你可以使用这个:
REASSIGN OWNED BY old_role [, ...] TO new_role
但如果当前的所有者是postgres,你肯定会得到错误,所以你必须使用@dvanrensburg回答,但如果你想在相同的sql中执行命令,可以根据需要使用这些命令:
数据库
ALTER DATABASE target_database OWNER TO new_onwer;
表
DO
LANGUAGE plpgsql
$$
DECLARE
stmt text;
BEGIN
FOR stmt IN
WITH temp as (
SELECT 'ALTER TABLE '|| schemaname || '."' || tablename ||'" OWNER TO newuser' as command
FROM pg_tables WHERE NOT schemaname IN ('pg_catalog', 'information_schema')
ORDER BY schemaname, tablename )
SELECT command from temp

序列

WITH schema_names as(
SELECT distinct(schemaname) FROM pg_tables WHERE NOT schemaname IN ('pg_catalog', 'information_schema')

还要注意数据库中可能需要更改成员关系的函数和其他组件
函数和触发函数
DO
LANGUAGE plpgsql
$$
DECLARE
stmt text;
BEGIN
FOR stmt IN
WITH temp as(
SELECT 'alter function '||nsp.nspname||'.'||p.proname||'('||pg_get_function_identity_arguments(p.oid)||') owner to newuser;' as command
FROM pg_proc p
JOIN pg_namespace nsp ON p.pronamespace = nsp.oid
WHERE NOT nsp.nspname IN ('pg_catalog', 'information_schema'))
SELECT command FROM temp
LOOP
EXECUTE stmt;
END LOOP;
END;
