PostgreSQL 10.8 Mac详细介绍

PostgreSQL (也叫 Postgres)是一个自由的对象-关系数据库服务器(数据库管理系统)，它在灵活的 BSD-风格许可证下发行。它提供了相对其他开放源代码数据库系统(比如 MySQL 和 Firebird)，和对专有系统比如 Oracle、Sybase、IBM 的 DB2 和 Microsoft SQL Server的一种选择。

PostgreSQL 不寻常的名字导致一些读者停下来尝试拼读它，特别是那些把SQL拼读为"sequel"的人。PostgreSQL 开发者把它拼读为 "post-gress-Q-L"。(Audio sample, 5.6k MP3)。它也经常被简略念为 "postgres"。

PostgreSQL 使用名为 PostgreSQL 的许可证，该许可证与 BSD/MIT 类似。
