Installation

We need to install PostgreSQL on our system to use it. The following are the steps on how to install PostgreSQL:

1. First, install PostgreSQL from https://www.postgresql.org/download/.
2. Then install PostGIS from https://postgis.net/install/.

Remember the password specified while installing PostgreSQL and the database name specified while installing PostGIS because we need those details later to connect to the database from our Spring application.
