Answer 1

I got the solution ..

Downladed the Linux package(postgresql-9.1.11-1-linux-x64.run) from the link below and execute as root,

./postgresql-9.1.11-1-linux-x64.run

All the dependencies are included with this package.

The database server rpm which you are trying to install has a number of dependencies. While you could install then all manually, by downloading them one at a time and installing them, that's definitely not the easiest way.

I recommended you install it via yum. Full instructions are given on the postgresql wiki. Yum will handle the task of downloading all the needed rpms and installing them.
