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。

参见REASSIGN OWNED命令
注意:正如@trygvis在下面的回答中提到的,REASSIGN OWNED命令至少在8.2版本中就可用了,而且是一个更简单的方法。
因为要更改所有表的所有权,所以可能还需要视图和序列。以下是我所做的:
表:
for tbl in `psql -qAt -c "select tablename from pg_tables where schemaname = 'public';" YOUR_DB` ; do psql -c "alter table \"$tbl\" owner to NEW_OWNER" YOUR_DB ; done
序列:
for tbl in `psql -qAt -c "select sequence_name from information_schema.sequences where sequence_schema = 'public';" YOUR_DB` ; do psql -c "alter sequence \"$tbl\" owner to NEW_OWNER" YOUR_DB ; done
视图:
for tbl in `psql -qAt -c "select table_name from information_schema.views where table_schema = 'public';" YOUR_DB` ; do psql -c "alter view \"$tbl\" owner to NEW_OWNER" YOUR_DB ; done
您可能会DRY它一点,因为alter语句对所有三个都是相同的。
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
pg_dump as insert statements
pg_dump -d -O database filename
-d ( data as inserts ) -O ( capital O is no owner )
然后使用以下命令将备份文件输送回PostgreSQL:
psql -d database -U username -h hostname < filename
由于没有包含所有者,因此创建的所有表、模式等都是在指定的登录用户下创建的。
我了解到这也是一个在PostgreSQL版本之间迁移的好方法。
http://archives.postgresql.org/pgsql-bugs/2007-10/msg00234.php也是一个很好的快速解决方案,适用于一个数据库中的多个模式:
表
SELECT 'ALTER TABLE '|| schemaname || '."' || tablename ||'" OWNER TO my_new_owner;'
FROM pg_tables WHERE NOT schemaname IN ('pg_catalog', 'information_schema')
ORDER BY schemaname, tablename;
序列
SELECT 'ALTER SEQUENCE '|| sequence_schema || '."' || sequence_name ||'" OWNER TO my_new_owner;'
FROM information_schema.sequences WHERE NOT sequence_schema IN ('pg_catalog', 'information_schema')
ORDER BY sequence_schema, sequence_name;
的观点
SELECT 'ALTER VIEW '|| table_schema || '."' || table_name ||'" OWNER TO my_new_owner;'
FROM information_schema.views WHERE NOT table_schema IN ('pg_catalog', 'information_schema')
ORDER BY table_schema, table_name;
物化视图
基于这个答案
SELECT 'ALTER TABLE '|| oid::regclass::text ||' OWNER TO my_new_owner;'
FROM pg_class WHERE relkind = 'm'
ORDER BY oid;
这将生成所有必需的ALTER TABLE / ALTER SEQUENCE / ALTER VIEW语句,复制这些语句并将它们粘贴回plsql以运行它们。
检查你在psql中的工作,执行以下操作:
\dt *.*
\ds *.*
\dv *.*
如果希望在一条sql语句中完成,则需要定义一个exec()函数,如http://wiki.postgresql.org/wiki/Dynamic_DDL中所述
CREATE FUNCTION exec(text) returns text language plpgsql volatile
AS $f$
BEGIN
EXECUTE $1;
RETURN $1;
END;
$f$;
然后你可以执行这个查询,它会改变表,序列和视图的所有者:
SELECT exec('ALTER TABLE ' || quote_ident(s.nspname) || '.' ||
quote_ident(s.relname) || ' OWNER TO $NEWUSER')
FROM (SELECT nspname, relname
FROM pg_class c JOIN pg_namespace n ON (c.relnamespace = n.oid)
WHERE nspname NOT LIKE E'pg\\_%' AND
nspname <> 'information_schema' AND
relkind IN ('r','S','v') ORDER BY relkind = 'S') s;
$NEWUSER是新所有者的postgresql新名称。
在大多数情况下,您需要超级用户才能执行此操作。可以通过将所有者从您自己的用户更改为您所属的角色组来避免这种情况。
感谢RhodiumToad在#postgresql上的帮助。
从PostgreSQL 9.0开始,你可以GRANT [priv名称]ON ALL[对象类型]in SCHEMA,其中[priv名称]是典型的SELECT, INSERT, UPDATE, DELETE等,[对象类型]可以是其中之一:
表 序列 功能
PostgreSQL的GRANT和REVOKE文档对此有更详细的说明。在某些情况下,仍然需要使用涉及系统编目(pg_catalog.pg_*)的技巧,但这种情况并不常见。我经常做以下事情:
开始一个事务来修改privs 将数据库的所有权更改为“DBA角色” 将schema的所有权更改为“DBA角色” 撤销所有角色的所有表、序列和函数上的所有私权 将相关/适当表上的SELECT、INSERT、UPDATE、DELETE权限授予适当的角色 提交DCL事务。
@Alex Soto的答案是正确的,@Yoav Aner上传的要点也有效,前提是在表/视图名称中没有特殊字符(在postgres中是合法的)。
你需要转义它们来工作,我已经上传了一个要点:https://gist.github.com/2911117
被接受的解决方案不关心函数所有权,下面的解决方案会关心所有的问题(在回顾时,我注意到它类似于上面的@magiconair)
echo "Database: ${DB_NAME}"
echo "Schema: ${SCHEMA}"
echo "User: ${NEW_OWNER}"
pg_dump -s -c -U postgres ${DB_NAME} | egrep "${SCHEMA}\..*OWNER TO"| sed -e "s/OWNER TO.*;$/OWNER TO ${NEW_OWNER};/" | psql -U postgres -d ${DB_NAME}
# do following as last step to allow recovery
psql -U postgres -d postgres -c "ALTER DATABASE ${DB_NAME} OWNER TO ${NEW_OWNER};"
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。
很简单,试试看…
select 'ALTER TABLE ' || table_name || ' OWNER TO myuser;' from information_schema.tables where table_schema = 'public';
您可以在PostgreSQL 9中尝试以下操作
DO $$DECLARE r record;
BEGIN
FOR r IN SELECT tablename FROM pg_tables WHERE schemaname = 'public'
LOOP
EXECUTE 'alter table '|| r.tablename ||' owner to newowner;';
END LOOP;
END$$;
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。
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。
非常简单
Su - postgres psql 重新分配[old_user]到[new_user]; \c[你的资料库] 重新分配[old_user]到[new_user];
完成了。
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
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 $$DECLARE r record;
DECLARE
v_schema varchar := 'public';
v_new_owner varchar := '<NEW_OWNER>';
BEGIN
FOR r IN
select 'ALTER TABLE "' || table_schema || '"."' || table_name || '" OWNER TO ' || v_new_owner || ';' as a from information_schema.tables where table_schema = v_schema
union all
select 'ALTER TABLE "' || sequence_schema || '"."' || sequence_name || '" OWNER TO ' || v_new_owner || ';' as a from information_schema.sequences where sequence_schema = v_schema
union all
select 'ALTER TABLE "' || table_schema || '"."' || table_name || '" OWNER TO ' || v_new_owner || ';' as a from information_schema.views where table_schema = v_schema
union all
select 'ALTER FUNCTION "'||nsp.nspname||'"."'||p.proname||'"('||pg_get_function_identity_arguments(p.oid)||') OWNER TO ' || v_new_owner || ';' as a from pg_proc p join pg_namespace nsp ON p.pronamespace = nsp.oid where nsp.nspname = v_schema
LOOP
EXECUTE r.a;
END LOOP;
END$$;
根据@rkj, @ alannrose, @SharoonThomas, @user3560574提供的答案和@ a_horis_with_no_name的回答
非常感谢。
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';

END$$;
根据elysch的回答,这里有一个针对多个模式的解决方案:
DO $$
DECLARE
r record;
i int;
v_schema text[] := '{public,schema1,schema2,schema3}';
v_new_owner varchar := 'my_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 = ANY (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 = ANY (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 = ANY (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 = ANY (v_schema)
union all
select 'ALTER DATABASE "' || current_database() || '" OWNER TO ' || v_new_owner
LOOP
EXECUTE r.a;
END LOOP;
FOR i IN array_lower(v_schema,1) .. array_upper(v_schema,1)
LOOP
EXECUTE 'ALTER SCHEMA "' || v_schema[i] || '" OWNER TO ' || v_new_owner ;
END LOOP;
END
$$;
与@AlexSoto的函数方法相同:
IFS=$'\n'
for fnc in `psql -qAt -c "SELECT '\"' || p.proname||'\"' || '(' || pg_catalog.pg_get_function_identity_arguments(p.oid) || ')' FROM pg_catalog.pg_namespace n JOIN pg_catalog.pg_proc p ON p.pronamespace = n.oid WHERE n.nspname = 'public';" YOUR_DB` ; do psql -c "alter function $fnc owner to NEW_OWNER" YOUR_DB; done
我不得不改变表,视图和序列的所有权,并发现@rjk发布的伟大解决方案工作得很好-尽管有一个细节: 如果对象名称是大小写混合的(例如。"TableName"),这将失败,并报错"not found"。 为了避免这种情况,可以像这样用' " '来包装对象名称:
表
SELECT 'ALTER TABLE \"'|| schemaname || '.' || tablename ||'\" OWNER TO my_new_owner;'
FROM pg_tables WHERE NOT schemaname IN ('pg_catalog', 'information_schema')
ORDER BY schemaname, tablename;
序列
SELECT 'ALTER SEQUENCE \"'|| sequence_schema || '.' || sequence_name ||'\" OWNER TO my_new_owner;'
FROM information_schema.sequences WHERE NOT sequence_schema IN ('pg_catalog', 'information_schema')
ORDER BY sequence_schema, sequence_name;
的观点
SELECT 'ALTER VIEW \"'|| table_schema || '.' || table_name ||'\" OWNER TO my_new_owner;'
FROM information_schema.views WHERE NOT table_schema IN ('pg_catalog', 'information_schema')
ORDER BY table_schema, table_name;
对于表,你必须循环:
for tbl in `psql -qAt -c "select tablename from pg_tables where schemaname = 'public';" YOUR_DB` ; do psql -U postgres -c "alter table \"$tbl\" owner to NEW_USER" YOUR_DB ; done
重新分配所有没有为我工作,因为我想改变由postgres拥有的表。
我最终使用Alex的方法,但我想从psql中做到这一点。下面这些对我来说就足够了。
DO $$
DECLARE
rec record;
BEGIN
FOR rec in
SELECT *
FROM pg_tables
where schemaname = 'public'
LOOP
EXECUTE 'alter table ' || quote_ident(rec.tablename) || ' owner to new_owner';
END LOOP;
END
$$;
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。
从其他人的讨论来看,他们不同意我的问题。如前所述,如果所有者是postgres, REASSIGN OWNED不工作。所以,受之前讨论的启发,我写了这个脚本:

;$alt_own_onall$;
在PSQL下使用它: SELECT alt_own_onall ('new_role_name'); 你必须把法语信息翻译成你自己的语言。 适用于pg 9.5
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:
格兰特·olduser
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:
