[root@me ~]# yum info postgresql93-docs.x86_64

            : PostgreSQL.  Currently, this includes the main documentation in PDF format
            : and source files for the PostgreSQL tutorial.

和cheked docs：

[root@me ~]# find / -name *.pdf
/usr/share/doc/python27-babel-0.9.4/doc/logo.pdf
/usr/share/doc/libtasn1-2.3/libtasn1.pdf

问：包装描述不好或目录结构在哪里可以找到pdf文件？..
