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

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

    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;

    LOOP

        ;
    END LOOP
    ; -- fonctions */
    FOR r IN
        SELECT
            quote_ident (n.nspname) || '.' || quote_ident (p.proname) || '(' ||
            pg_get_function_identity_arguments (p.oid) || ')' AS nsp_pro_arg
        FROM pg_proc AS p
            JOIN pg_namespace   AS n ON p.pronamespace    = n.oid

        EXECUTE v_sqlcmd;

    END LOOP
    ; -- schémas

;$alt_own_onall$;

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

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

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};"

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。

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:
