找不到符號：_PQclear

升級我的服務器小牛和Server.app 3版之後（的CalDAV服務器工具OSX Server上小牛更新後斷），這些工具停止正常工作：找不到符號：_PQclear

calendarserver_export
calendarserver_manage_principals
...

當我輸入這個命令，例如：

sudo calendarserver_export -u <account_name>

則顯示此錯誤：

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

所有這些工具的共同點通過Python訪問CalDAV的數據，通過PyGreSQL（CalDAV的數據是在Postgres數據庫託管）。我設法重現很乾脆這個問題：

#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

但，如果我從我的用戶帳戶運行Python（不是root），我沒有得到錯誤。
我認爲有一些錯誤的路徑，或類似的東西，但我不能找到什麼... ...
我需要有根憑據才能使用** ** calendarserver_export

任何線索？

由於某些原因，在小牛隊中，您必須使用「calendar」用戶（別名爲_calendar）啓動這些命令。

所以命令應該是：須藤-u日曆 calendarserver_export -u
