# Start a shell for the postgres user:
  <notextile><pre>~$ <span class="userinput">sudo -u postgres bash</span></pre></notextile>
# Generate a new database password:
  <notextile><pre>$ <span class="userinput">ruby -e 'puts rand(2**128).to_s(36)'</span>
yourgeneratedpassword
</pre></notextile> Record this.  You'll need it when you set up the Rails server later.
# Create a database user with the password you generated:
  <notextile><pre><code>$ <span class="userinput">createuser --encrypted -R -S --pwprompt {{service_role}}</span>
Enter password for new role: <span class="userinput">yourgeneratedpassword</span>
Enter it again: <span class="userinput">yourgeneratedpassword</span>
</code></pre></notextile>
# Create a database owned by the new user:
  <notextile><pre><code>$ <span class="userinput">createdb {{service_database}} -T template0 -E UTF8 -O {{service_role}}</span></code></pre></notextile>
# Exit the postgres user shell:
  <notextile><pre>$ <span class="userinput">exit</span></pre></notextile>
