找不到符号：_PQclear

升级我的服务器小牛和Server.app 3版之后（的CalDAV服务器工具OSX Server上小牛更新后断），这些工具停止正常工作：找不到符号：_PQclear

calendarserver_export
calendarserver_manage_principals
...

当我输入这个命令，例如：

sudo calendarserver_export -u <account_name>

则显示此错误：

Traceback (most recent call last): 
    File "/Applications/Server.app/Contents/ServerRoot/usr/sbin/calendarserver_export", line 32, in <module> 
    from calendarserver.tools.export import main

所有这些工具的共同点通过Python访问CalDAV的数据，通过PyGreSQL（CalDAV的数据是在Postgres数据库托管）。我设法重现很干脆这个问题：

#login with root 
bob $ sudo -i 
#launch python and import pg (postgres module for python) 
root $ python 
Python 2.7.5 (default, Mar 9 2014, 22:15:05)

Type "help", "copyright", "credits" or "license" for more information. 
>>> import pg 
Traceback (most recent call last): 
    File "<stdin>", line 1, in <module> 
    File "/Library/Python/2.7/site-packages/PyGreSQL-4.1.1-py2.7-macosx-10.9-intel.egg/pg.py", line 31, in <module>

    Expected in: flat namespace 
in /Library/Python/2.7/site-packages/PyGreSQL-4.1.1-py2.7-macosx-10.9-intel.egg/_pg.so

但，如果我从我的用户帐户运行Python（不是root），我没有得到错误。
我认为有一些错误的路径，或类似的东西，但我不能找到什么... ...
我需要有根凭据才能使用** ** calendarserver_export

任何线索？

由于某些原因，在小牛队中，您必须使用“calendar”用户（别名为_calendar）启动这些命令。

所以命令应该是：须藤-u日历 calendarserver_export -u
