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

@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

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:

CREATE OR REPLACE FUNCTION public.alt_own_onall (v_new_owner text)
    RETURNS void
    LANGUAGE plpgsql
AS $alt_own_onall$
-- ALTer OWNer ON ALL objects
DECLARE
    r           RECORD;
    v_sqlcmd    TEXT; -- commande SQL
    b_modif     BOOLEAN DEFAULT false;    -- si au moins une modif
BEGIN
    v_new_owner := quote_ident (v_new_owner);
    IF v_new_owner NOT IN
        (SELECT role_name FROM information_schema.enabled_roles WHERE role_name <>'postgres')
        THEN
            RAISE WARNING '[%] est inconnu', v_new_owner;
            RETURN;
    END IF
    ; -- tables
    RAISE INFO 'Le nouveau propriétaire des tables, vues, fonctions, schémas et de la base va être [%]', v_new_owner
    ;
    FOR r IN
        SELECT quote_ident(schemaname) || '.' || quote_ident(tablename) sch_tbl
        FROM pg_catalog.pg_tables
        WHERE schemaname !~'^(pg_|information)' AND tableowner <> v_new_owner
    LOOP
        v_sqlcmd := 'ALTER TABLE ' || r.sch_tbl || ' OWNER TO ' || v_new_owner || ';';
        RAISE INFO 'Exécution de [%]', v_sqlcmd;
        EXECUTE v_sqlcmd;
        b_modif := true;
    END LOOP
    ; -- views
    FOR r IN
        SELECT quote_ident(schemaname) || '.' || quote_ident(viewname) v_sch_nam
        FROM pg_catalog.pg_views
        WHERE schemaname !~'^(pg_|information)' AND viewowner <> v_new_owner
    LOOP
        v_sqlcmd := 'ALTER VIEW '|| r.v_sch_nam ||' OWNER TO ' || v_new_owner || ';';
        RAISE INFO 'Exécution de [%]', v_sqlcmd;
        EXECUTE v_sqlcmd;
        b_modif := true;
    END LOOP
    ; -- séquences

    FOR r IN

;$alt_own_onall$;

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

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。

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

序列

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

的观点

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

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

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 *.*
