Create A Postgres Database

Connect to the main postgres database with a user that has create database privileges via:

psql -U user_name -d postgres

(Or, psql postgres if your setup for that)

Run:

CREATE DATABASE your_database_name;

The database is made from a clone of the template1 database. So, any changes made there will show up in your new database.

NOTES:

You can check what permissions users have with \du when logged into the database
