To install latest version of postgresql we first we need to add pgdg repository to list of repositories open terminal and fire following commands, you need to be root.

wget http://yum.pgsqlrpms.org/reporpms/8.4/pgdg-redhat-8.4-1.noarch.rpm
rpm -Uhv pgdg-redhat-8.4-1.noarch.rpm

Once repository is installed properly use yum to install postgresql as shown below

Few days back I was trying to create database in a batch job using createdb.exe and I encountered this problem createdb.exe prompts for password and there is no way of passing password from command line as an argument.
I tried to find out how to do this but in vein there is no way you can pass password as an command line argument; than after looking around for sometime and googling I found two ways of doing it

Setting up PGPASSWORD environment variable : This method is not preferable as it’s insecure more for further details read this

Setting up password in pgpass.conf : The file is to be located
%APPDATA%\postgresql\pgpass.conf

File has the following format

hostname:port:database:username:password

Each of the first four fields may be a literal value, or *, which matches anything.
