I found default host:port is localhost:8888, but by giving -h option, we can't see how to use the command paramter; second, I didn't get it by reading the sentence: _You...

出现UnicodeEncodeError: 'ascii' codec can't encode characters in position 5-10: ordinal not in range(128) 应该需要加上: import sys reload(sys) sys.setdefaultencoding('utf-8')

学习一项新项目代码,我倾向先看其test case 是什么样的,它不仅能帮忙快速了解各个函数是如何拼接在一起,如何达到预期的值的,而且让我们了解到开发者是如何证明代码是OK的,将来若被破坏是容易被发现的。 然而发现 pg 的test case 很少用 c 写的,这也能理解,毕竟 没有像gtest 那样的常用框架。大部分是用 perl 写的,目前还没法看懂。 我现在不太确定那些用 perl 写的case 的价值,值不值得我花点时间去学习perl 以读懂 pg 的test case。 您所了解到pg 社区重视代码的自动化测试、回归测试等吗?我怎么感觉源码里的 `src/test` cases 太少了,似乎没有大规模覆盖 `src/backend` 里的那么多源码逻辑?

I did a careful comparison for `ReadonlyUint64Histogram` and `ReadonlyFloat64Histogram` , and found no significant difference between them. See the following compare result: ![image](https://user-images.githubusercontent.com/5157680/87024546-d5770f80-c20b-11ea-8758-0102a1c6d69f.png) ![image](https://user-images.githubusercontent.com/5157680/87024582-e45dc200-c20b-11ea-8276-4ff6d22d6ecb.png) Just change between `float64` and `uint64`,...

Hi, @apkar It seems that the repo hasn't been update for a long time. Any roadmap in the community ?

Hi. I have a C++ member function `foo` in class A, `void A::foo();`. And I call it in a function `bar`. ``` void bar() { a.foo(); } ``` When I...

作者是设计了几个场景,来看各个框架的qps和latency,如果框架A qps大,latency大,框架B qps小,latency小,则究竟谁好呢? 我从多个地方了解到,比较延时是要保证吞吐一致的。不知作者是怎么理解的

For some dangerous command such as flushall, flushdb, there's odds that they're renamed by other commands by operator. Could that be supported ?

Hi. I find this repo and feel good. I'm not familiar with sqlite original code and wonder whether you restructure original C code to C++. Another question, about wal policy,...
