The app uses its own database (operations_hub) and its own user (opshub), so it
won't touch anything else on your machine.
Connect as the postgres superuser (it'll prompt for the password you set during install):
psql -U postgresAt the postgres=# prompt, paste these three lines. You can change the password, just
use the same one in .env later:
CREATE USER opshub WITH PASSWORD 'opshub_dev_password';
CREATE DATABASE operations_hub OWNER opshub;
\qThat's it. The tables are created automatically in the next step.
