# 什麼是 PostgreSQL？ 怎麼發音？Postgres 又是什麼？

PostgreSQL 發音為 Post-Gres-Q-L。 （好奇如何說「PostgreSQL」，請聽：[MP3語音檔](http://www.postgresql.org/files/postgresql.mp3)。）

PostgreSQL 是一個物件導向關連式資料庫系統，具有傳統專業資料庫系統的特性，也包含在先進 DBMS 系統中的強化功能。PostgreSQL 是免費的，而且是完整開放原始碼的。

PostgreSQL 的開發大多是由遍布全球的志願者開發團隊進行的，並通過網際網路進行討論。這是一個社群專案，不受任何公司控制。想要參與的話，請參閱開發常見問題[開發常見問題](https://wiki.postgresql.org/wiki/Developer_FAQ).

Postgres 是 PostgreSQL 廣泛使用的暱稱。這是伯克萊專案的原始名稱，比其他暱稱更受歡迎。如果你發現「PostgreSQL」難以發音，請試試看「Postgres」。

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://faq.postgresql.tw/shi-mo-shi-postgresql-zen-mo-fa-yin-postgres-you-shi-shi-mo.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
