I am using pgadmin 3 software for database. I would like to connect this database to my website so that I can retrieve ,add delete database entries from the website
If you would like to operate postgres database from a browser client, you must use server side script(s) which offers postgres API. There are several possible solutions, some of them:
- Laravel (PHP)
- Django (Python)
- Python + Psycopg
- PHP & PDO
It is impossible to explain more details here.
