你好

为什么PostgreSQL选择像复制这样的功能，


这是因为有多个版本的复制，每个

有利有弊。社区不希望支持其中任何一个。

全文索引和由源外的其他人维护的GIS？


我不确定这可能是许可问题。

你好

为什么PostgreSQL选择具有复制，全文索引和GIS维护等功能在sourcetree之外的其他人？

好​​吧，在复制的情况下，目前有大约六打复制

解决方案每个都以不同的方式提供复制，而不是以最终复制方式提供复制。 ...另外，
PostgreSQL设计为可扩展的，所以FTI和GIS之类的东西可以在服务器本身启动并运行之后插入* b $ b。他们是''添加

ons''，而不是''核心功能''......

你好

为什么PostgreSQL会选择它s具有复制，
全文索引和GIS源外的其他人维护的功能吗？

因为这些功能非常多样化。尤其是复制，其中
是一堆不同的技术解决方案，可以解决十几个问题。在这些问题上，没有任何一种尺寸适合所有人，因为他们不属于

数据库服务器的核心发行版。

对于我正在计划的下一个复制系统，核心服务器需要进行一些更改。但是这些将被简化为钩子和API

，这将更加通用，并且可供讨论，以提供大多数复制扩展所需的

基础设施。

Hello

Why is it that PostgreSQL chooses to have features like replication,
fulltext indexing and GIS maintained by others outside of the sourcetree?

I appreciate any answers.

Thank you.

Well this is because there are multiple versions of replication and each
has pros and cons. The community does not wish to endorse any of them.
fulltext indexing and GIS maintained by others outside of the sourcetree?
This I am unsure of although it may be licensing issues.

well, in the case of replication, there are about a half dozen replication
solutions currently out there, each providing replication in a different
way, and non of them being "the definitive replication" ... also,
PostgreSQL was designed to be extensible, so stuff like FTI and GIS can be
plugged in *after* the server itself is up and running ... they are ''add
ons'', not ''core features'' ...

Because those are very diverse features. Replication especially, which
is a bunch of different technical solutions for more than a dozen
problems. In these matters there is no one size that fits all, and
because of that they don''t belong into the core distribution of the
database server.

For the next replication system I am planning, there need to be some
changes to the core server. But these will be reduced to hooks and APIs
that will be more general and open to discussion to provide the
infrastructure requited by the majority of replication extensions.
