+Start PostgreSQL. Note that the following is just an example to run PostgreSQL,
+you should ensure you use your own user and credentials when setting it up.
+```sh
+sudo postgresql-setup --initdb
+sudo systemctl start postgresql
+sudo -u postgres -i
+# psql
+postgres=# \password postgres
+Enter new password:
+Enter it again:
+postgres=# CREATE USER myuser WITH PASSWORD 'mypass';
+postgres=# CREATE DATABASE mydb;
+postgres=# GRANT ALL PRIVILEGES ON DATABASE mydb to myuser;
+postgres=# \q
+sudo systemctl restart postgresql
+```
+
