postgresql jsonb查询更新问题，jsonb_insert函数

[zysaaaaa]

基于pg 9.4，有如下表，data是jsonb类型。
CREATE TABLE users (
id serial PRIMARY KEY,
data jsonb
);

INSERT INTO "public"."users" VALUES ('1', '{"Address": {"City": "Skopje", "Country": "Macedonia"}, "LastName": "Doe", "FirstName": "John"}');

然后根据官方文档https://www.postgresql.org/docs/current/functions-json.html的jsonb_insert函数，
，我想要在data字段里再插入一个key，value，执行如下sql：

UPDATE users
SET DATA = jsonb_set (DATA, '{Age}', '"30"', TRUE)
WHERE
ID = 1;
报错:
[Err] ERROR: function jsonb_set(jsonb, unknown, unknown, boolean) does not exist
LINE 2: SET DATA = jsonb_set (DATA, '{Age}', '"30"', TRUE)
^
HINT: No function matches the given name and argument types. You might need to add explicit type casts.

希望各位回答一下。
