在PostgreSQL中同时修改所有表上的OWNER

Question

如何修改PostgreSQL数据库中所有表的所有者？

我试过,ALTER TABLE * OWNER TO new_owner但它不支持星号语法.

Answer 1

您可以使用该REASSIGN OWNED命令.

概要:

REASSIGN OWNED BY old_role [, ...] TO new_role

这会将所有拥有的对象更改old_role为新角色.您不必考虑用户拥有的对象类型,它们都将被更改.请注意,它仅适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.

它可以回到至少8.2.他们的在线文档只能追溯到很久以前.

Answer 2

见REASSIGN OWNED命令

注意:正如@trygvis 在下面的答案中提到的,该REASSIGN OWNED命令至少从版本8.2开始可用,并且是一种更容易的方法.

由于您要更改所有表的所有权,因此您可能也需要视图和序列.这是我做的:

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

浏览次数:

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

由于alter语句对于所有三个语句都相同,所以你可能会稍微干一点.

Answer 3

这个: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;

查看

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;

物化观点

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,复制它们并将它们粘贴回plsql以运行它们.

通过执行以下操作检查psql中的工作:

\dt *.*
\ds *.*
\dv *.*

Answer 4

如果你想在一个sql语句中执行它,你需要定义一个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;
$f$;

然后您可以执行此查询,它将更改表,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,您需要成为超级用户才能执行此操作.您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.

Answer 5

如果当前所有者不是 postgres，您可以使用以下命令：

REASSIGN OWNED BY old_role [, ...] TO new_role

但是如果当前所有者是 postgres，你肯定会得到错误，所以你必须使用 @dvanrensburg 答案，但如果你想在同一个 sql 中执行命令，请根据需要使用这些命令：

数据库

ALTER DATABASE target_database OWNER TO new_onwer;

表格

DO
LANGUAGE plpgsql
$$
DECLARE
  stmt text;
BEGIN
  FOR stmt IN
    WITH temp as (
    SELECT 'ALTER TABLE '|| schemaname || '."' || tablename ||'" OWNER TO newuser' as command
    FROM pg_tables WHERE NOT schemaname IN ('pg_catalog', 'information_schema')
    ORDER BY schemaname, tablename )
    SELECT command from temp
  LOOP
    EXECUTE stmt;
  END LOOP;
END;
$$;

序列

DO
LANGUAGE plpgsql
$$
DECLARE
  stmt text;
BEGIN
  FOR stmt IN
    WITH temp as (
    SELECT 'ALTER SEQUENCE '|| sequence_schema || '."' || sequence_name ||'" OWNER TO newuser;' as command
    FROM information_schema.sequences WHERE NOT sequence_schema IN ('pg_catalog', 'information_schema')
    ORDER BY sequence_schema, sequence_name)
    select command from temp
  LOOP
    EXECUTE stmt;
  END LOOP;
END;
$$;

意见

DO
LANGUAGE plpgsql
$$
DECLARE
  stmt text;
BEGIN
  FOR stmt IN
    WITH temp as (
    SELECT 'ALTER VIEW '|| table_schema || '."' || table_name ||'" OWNER TO newuser;' as command
    FROM information_schema.views WHERE NOT table_schema IN ('pg_catalog', 'information_schema')
    ORDER BY table_schema, table_name)
    select command from temp
  LOOP
    EXECUTE stmt;
  END LOOP;
END;
$$;

模式

DO
LANGUAGE plpgsql
$$
DECLARE
  stmt text;
BEGIN
  FOR stmt IN
    WITH schema_names as(
    SELECT distinct(schemaname) FROM pg_tables WHERE NOT schemaname IN ('pg_catalog', 'information_schema')
    ORDER BY schemaname)
    SELECT 'ALTER SCHEMA '|| schemaname ||' OWNER TO newuser;' as command
    FROM schema_names
  LOOP
    EXECUTE stmt;
  END LOOP;
END;
$$;

另请注意可能需要更改成员资格的数据库功能和其他组件

功能和触发功能

    DO
    LANGUAGE plpgsql
    $$
    DECLARE
      stmt text;
    BEGIN
      FOR stmt IN
        WITH temp as(
        SELECT 'alter function '||nsp.nspname||'.'||p.proname||'('||pg_get_function_identity_arguments(p.oid)||') owner to newuser;' as command
        FROM pg_proc p
        JOIN pg_namespace nsp ON p.pronamespace = nsp.oid
        WHERE NOT  nsp.nspname IN ('pg_catalog', 'information_schema'))
        SELECT command FROM temp
      LOOP
        EXECUTE stmt;
      END LOOP;
    END;
    $$;

Answer 6

我最近不得不更改数据库中所有对象的所有权.虽然表,视图,触发器和序列有些容易更改,但上述方法对于函数失败,因为签名是函数名称的一部分.当然,我有一个MySQL背景,并不熟悉Postgres.

但是,pg_dump允许您只转储模式,这包含ALTER xxx所有者yyy; 你需要的陈述.这是关于这个话题的shell魔术

pg_dump -s YOUR_DB | grep -i 'owner to' | sed -e 's/OWNER TO .*;/OWNER TO NEW_OWNER;/i' | psqL YOUR_DB

Answer 7

非常简单

1. su - postgres
2. PSQL
3. [old_user]对[new_user]进行重新分配;
4. \ c [您的数据库]
5. [old_user]对[new_user]进行重新分配;

完成.

Answer 8

很简单,试试吧......

 select 'ALTER TABLE ' || table_name || ' OWNER TO myuser;' from information_schema.tables where table_schema = 'public';

Answer 9

我喜欢这个,因为它修改表,视图,序列和功能有一定的所有者架构在一个去(在一个SQL语句),而无需创建一个功能,你可以直接使用它的pgAdmin III和PSQL:

(在PostgreSql v9.2中测试过)

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

非常感谢.

更好的是:还要更改数据库和模式所有者.

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

Answer 10

您可以在PostgreSQL 9中尝试以下操作

DO $$DECLARE r record;
BEGIN
    FOR r IN SELECT tablename FROM pg_tables WHERE schemaname = 'public'
    LOOP
        EXECUTE 'alter table '|| r.tablename ||' owner to newowner;';
    END LOOP;
END$$;

Answer 11

PostgreSQL中没有这样的命令.但你可以使用我前面描述的GRANTs 方法解决它.

Answer 12

我不得不更改表，视图和序列的所有权，发现@rjk发布的出色解决方案可以正常工作-尽管有一个细节：如果对象名称是大小写混合的（例如“ TableName”），则将失败并显示“未找到”-错误。
为了避免这种情况，请使用“”将对象名称包装起来，如下所示：

桌子

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;

顺序

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;

观看次数

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;
