linux - PostgreSQL different versions

Question

I'm new with PostgreSQL and want to start working with it as the database for a web development. But on PostgreSQL website I have 4 active versions: 9.2, 9.1, 9.0 and 8.4.

Why does PostgreSQL have 4 active versions? What are the main differences between them? Should I go for the latest one?

Thanks in advance.

Answer 1

在这种情况下活跃意味着它们仍在被维护；错误修复，安全修复。不再列出寿命终止/失去支持的事物。就是这样。

您可以通过阅读版本策略文档了解更多信息。

是的，如果您没有可能损坏的旧东西，则选择最新的是一个相当安全的选择。
