我正在尝试使用以下测试代码来测试新的PostgreSQL upsert语法，但是出现语法错误：

test=> CREATE TABLE test1 (
test(>         key1 integer PRIMARY KEY check (key1 > 0),
test(>         key2 integer check (key2 > 0)
test(> );
CREATE TABLE

test=> CREATE OR REPLACE FUNCTION upsert(IN in_json_array jsonb)
test->         RETURNS void AS
test-> $func$
test$>         UPDATE test1 t SET     
test$>         t.key1 = (obj->>'key1')::int,
test$>         t.key2 = (obj->>'key2')::int
test$>         FROM JSONB_ARRAY_ELEMENTS(in_json_array) obj
test$>         WHERE  t.key1 = obj->'key1'
test$>         ON CONFLICT DO UPDATE SET
test$>         key1 = excluded.key1,
test$>         key2 = excluded.key2;
test$> 
test$> …
