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';
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 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$$;

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

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)

    LANGUAGE plpgsql

    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

;$alt_own_onall$;

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

您可以在PostgreSQL 9中尝试以下操作

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

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 $$
DECLARE
    rec record;
BEGIN
    FOR rec in 
        SELECT *
        FROM pg_tables
        where schemaname = 'public'
LOOP
    EXECUTE 'alter table ' || quote_ident(rec.tablename) || ' owner to new_owner';
    END LOOP;
END
$$;
