Thanks for your reply, i am totally new to Postgis.

we have Database, but not ready for Geocode use.  what i understood from different blog, we should have latitude and longitude either based on addresses, or postal code we have. However if I will get the lat and long, need to calculate earth distance to give  location based on user location. Formula i got, is calculating shortest distance, which always not true practically. Please address my concern, how i will get rid of these issues.

Regards,
Itishree
