Heroku pg:pull 无法填充模式

Question

所以我在pg:pull 上阅读了documentation，但似乎无法让它发挥作用。当我使用正确的参数运行命令时，我的 Heroku DB 被获取并创建了一个本地数据库，但模式没有在本地填充；例如，没有创建表、没有设置触发器、没有约束、没有数据等。

这是我的数据库的 heroku pg:info 日志：

=== HEROKU_POSTGRESQL_ORANGE_URL (DATABASE_URL)
Plan:        Hobby-dev
Status:      Available
Connections: 1
PG Version:  9.3.3
Created:     2014-04-02 19:24 UTC
Data Size:   7.4 MB
Tables:      6
Rows:        1376/10000 (In compliance)
Fork/Follow: Unsupported
Rollback:    Unsupported

这是我正在使用的命令：

PGUSER=postgres PGPASSWORD=password heroku pg:pull HEROKU_POSTGRESQL_ORANGE mylocaldb --app myappname

我不知道如何为PGUSER 和PGPASSWORD 设置环境变量（如果有人能指出我正确的方向，你会得到+1。我读了this question 并回答无济于事）。

mylocaldb已创建，但未填写schema。

这是运行命令后的pg_dump：

我需要在本地进行某种进一步的配置才能使其正常工作吗？如果这很重要，我正在为tsquery 使用自定义停用词字典，该字典尚未在这台机器上本地（尚未）设置...我怀疑这将是pg_dump 中的问题...任何非常感谢您的帮助！

编辑：我刚刚尝试在我的桌面上运行此命令，另一个本地站点已配置了所有内容。没有骨头。我得到完全相同的结果。以下是所述本地机器上which psql 的输出，以防万一：

$ which psql
/c/Program Files/PostgreSQL/9.3/bin/psql

Answer 1

@will 的答案在常规 Heroku 开发的情况下是完美的，但在 Private Space 的情况下失败。如Heroku Postgres and Heroku Private Spaces :: External connections 所述：

与我们的爱好、标准和高级层中的 Heroku Postgres 数据库不同，私有数据库不能通过本地计算机访问。

作为一种解决方法，您可以将数据库复制到非私有数据库，然后您可以将数据库转储到本地计算机。

Answer 2

我编写了pg:pull 和pg:push 命令。

pg:pull 和pg:push 都使用pg_dump 命令并将其直接传递给pg_restore (source code)。不幸的是，截至 2014 年 9 月此答案发布时，Windows 上的 pg:push,pull 存在问题。这些问题并非无法克服，因此，如果您稍后再回答此问题，请检查它是否已修复。

env 命令 used here 和 here 我不认为是在 Windows 上，这就是为什么你必须做 PGUSER 和 PGPASSWORD 的东西。然而env 的原因是pg_dump 需要与pg_restore 不同的环境变量。

我使用了一次a stab at fixing that，通过使用 popen 独立设置命令，然后将它们连接在一起而不是使用管道。但是，我无法让它正常工作，不得不停下来。

我很乐意查看所有的补丁并修复此问题，只需 @ 在 heroku/heroku 项目的拉取请求中提及我即可。

抱歉我没能解决这个问题:(

相反，在解决此问题之前，您可以直接分别使用pg_dump 和pg_restore 命令。作为一个两步过程，它更麻烦，并且必须查找远程凭据，但它可以完成工作。 gen_pg_*_command 方法中的链接源显示了如何使用pg_dump 和pg_restore。
