gitlab开发工具包：如何设置postgres？

我遵循了：

在CentOS 6.7机箱上，取得了很大的成功；但是，我无法运行postgres，因为克隆后的gitlab开发工具包没有postgres配置文件

如何设置postgres以使用gitlab开发工具包

我被困在上述链接说明的“安装后”步骤中，

bundle exec foreman start

告诉我：

[me1@gitlabdevkit gitlab-development-kit]$ bundle exec foreman start
16:47:49 redis.1            | started with pid 1275
16:47:49 postgresql.1       | started with pid 1276
16:47:49 nginx.1            | started with pid 1277
16:47:49 gitlab-workhorse.1 | started with pid 1280
16:47:49 redis.1            | [1275] 03 Nov 16:47:49 * Server started, Redis version 2.4.10
16:47:49 postgresql.1       | postgres cannot access the server configuration file "/home/me1/src/postgresql/data/postgresql.conf": No such file or directory
16:47:49 redis.1            | [1275] 03 Nov 16:47:49 # WARNING overcommit_memory is set to 0! Background save may fail under low memory condition. To fix this issue add 'vm.overcommit_memory = 1' to /etc/sysctl.conf and then reboot or run the command 'sysctl vm.overcommit_memory=1' for this to take effect.
16:47:49 redis.1            | [1275] 03 Nov 16:47:49 * The server is now ready to accept connections at /home/me1/src/gitlab-development-kit/redis/redis.socket

[me1@gitlabdevkit gitlab-development-kit]$ 

令人不快的兴趣线当然是：

    16:47:49 postgresql.1       | postgres cannot access the server configuration file "/home/me1/src/postgresql/data/postgresql.conf": No such file or directory

gitlab开发工具包中的任何文件似乎都不能满足这一需求。

答案就在这里：

简短版本（适用于gitlab开发工具包说明）的功能是：

mkdir -p postgresql/data
/usr/pgsql-9.3/bin/initdb -D postgresql/data

gitlab开发工具包文档中没有一个包含设置postgres的内容，必须假设开发人员能够找到上面的页面。由于我在问题中链接到的当前指南安装了postgresql 9.3，因此我在postgres网站上链接到该版本的相应文档页面
