Please find the steps that I have followed in Windows XP: Change your config file fastcgi_pass unix:/var/run/php5-fpm.sock; to fastcgi_pass 127.0.0.1:9000; Prepare PostgreSQL with below (this could have been done better):
D:\server\bin\pgsql\bin>createuser -s -d -r postgres
D:\server\bin\pgsql\bin>createdb -h localhost -U postgres restyaboard 
D:\server\bin\pgsql\bin>psql -h localhost -U postgres

CREATE USER restya WITH PASSWORD 'hjVl2!rGd';
ALTER DATABASE restyaboard OWNER TO restya;   
GRANT ALL PRIVILEGES ON DATABASE restyaboard TO restya;
GRANT ALL PRIVILEGES ON ALL TABLES IN SCHEMA public TO restya;  
GRANT ALL PRIVILEGES ON ALL SEQUENCES IN SCHEMA public TO restya;

D:\server\bin\pgsql\bin>psql -h localhost -d restyaboard -U restya -W < d:\server\www\restyaboard\sql\restyaboard_with_empty_data.sql
