deb http://apt.postgresql.org/pub/repos/apt/ wheezy-pgdg main我的 /etc/apt/sources.list 文件中已经有了。
我尝试过追踪依赖关系，但走到了死胡同。情况如下：
sudo apt-get install libpq-dev
(...)
The following packages have unmet dependencies:
libpq-dev : Depends: krb5-multidev but it is not going to be installed
sudo apt-get install krb5-multidev
(...)
The following packages have unmet dependencies:
krb5-multidev : Depends: libkrb5-3 (= 1.10.1+dfsg-5+deb7u3) but 1.13~alpha1+dfsg-1 is to be installed
Depends: libk5crypto3 (= 1.10.1+dfsg-5+deb7u3) but 1.13~alpha1+dfsg-1 is to be installed
Depends: libgssapi-krb5-2 (= 1.10.1+dfsg-5+deb7u3) but 1.13~alpha1+dfsg-1 is to be installed
sudo apt-get install libkrb5-3=1.10.1+dfsg-5+deb7u3
(...)
The following packages have unmet dependencies:
libkrb5-3 : Depends: libkrb5support0 (= 1.10.1+dfsg-5+deb7u3) but 1.13~alpha1+dfsg-1 is to be installed
问题就出在这里。如果我尝试安装所需的 libkrb5support0 版本，它会警告我，大约 1.6 GB 的软件将被删除，例如 texlive、nautilus、libreoffice 或 openssh。有什么想法吗？

Description-en: Development files for MIT Kerberos without Heimdal conflict
Kerberos is a system for authenticating users and services on a network.
Kerberos is a trusted third-party service. That means that there is a
third party (the Kerberos server) that is trusted by all the entities on
the network (users and services, usually called "principals").
.
This is the MIT reference implementation of Kerberos V5.
.
Most users wishing to build applications against MIT Kerberos should
install libkrb5-dev. However, that package conflicts with heimdal-dev.
This package installs libraries and headers in /usr/include/mit-krb5 and
/usr/lib/mit-krb5 and can be installed along side heimdal-multidev, which
provides the same facilities for Heimdal.
