postgre timezone problem

[jafer11]

Describe the bug
I use the PostgreSQL MCP service to connect to my database, and when calling the PostgreSQL MCP service, I get the following results:
{
"params": {
"sql": "SELECT "Date" AT TIME ZONE 'Asia/Shanghai' AS "本地日期", "numbers" AS "产量" FROM "ProductInspection" WHERE date_part('month', "Date") = 3 AND date_part('year', "Date") = 2025;"
},

The local date is in UTC format, but my local time is：
postgres=# show timezone;
TimeZone

Asia/Shanghai

Why does this happen? How can I solve this problem?
