从自定义声明的类型数组插入到PostgreSQL表中

我创建了一个自定义类型,如下所示:

CREATE TYPE employee AS (employee_id INTEGER, name VARCHAR(200), age INTEGER);

然后我创建一个函数,它接收一个此类数组作为参数:

CREATE FUNCTION insert_office(v_office_id INTEGER, v_office_name VARCHAR(400), v_employees employee[])
RETURNS void
AS $BODY$

INSERT INTO office (office_id, office_name)
VALUES(v_office_id, v_office_name)

--here I need to insert the array of employees (v_employees) into the employees table

$BODY$
LANGUAGE SQL;

假定已设置Employees表以匹配Employee类型的属性:

CREATE TABLE employee (employee_id INTEGER, name VARCHAR(200), age INTEGER)

如何简单地将此类型为employee的数组转移到employee表中?尽管尝试了好几次,我还是无法正确地理解语法。(PostgreSQL 9.6)
