我們有這個 postgresql 類型：create type order_input as (    item text,    quantity integer);而這個 postgresql 函數(shù)：create or replace function insert_into_orders(order_input[])returns void language plpgsql as $$declare     inserted_id integer;begin    insert into public.orders(orderdate)     values (now())     returning orderid into inserted_id;    insert into public.orderdetails(orderid, item, quantity)    select inserted_id, item, quantity    from unnest($1);end $$;要在 pgadmin-4 中執(zhí)行，我們運行：select insert_into_orders(    array[        ('Red Widget', 10),         ('Blue Widget', 5)    ]::order_input[]);我試圖弄清楚如何使用 pg-promise javascript 庫執(zhí)行 insert_into_orders 函數(shù)。我嘗試過執(zhí)行以下操作：const pgp = require("pg-promise")();const db = pgp(connectionObj);await db.func("insert_into_orders", [{item:"Red Widget", quantity:10}, {item:"Blue Widget", quantity:5}]但收到以下消息：{  "error": {    "message": "malformed array literal: \"{\"item\":\"Red Widget\", \"quantity\":10}\""  }}如果有人知道我必須如何為 pg-promise 構(gòu)建我的輸入，我將不勝感激
