The database server must be running at the
targeted host. Also, any default connection settings and environment
variables used by the <span class="application">libpq</span> front-end
library will apply.

<p> To destroy the database <code class="literal">demo</code> on the default
database server:

<pre class="screen"><code class="prompt">$ </code><strong class="userinput"><code>dropdb demo</code></strong>
<code class="computeroutput">DROP DATABASE</code></pre>

</p>
<p> To destroy the database <code class="literal">demo</code> using the

at the underlying command:
</p>
<pre class="screen"><code class="prompt">$ </code><strong class="userinput"><code>dropdb -p 5000 -h eden -i -e demo</code></strong>
<code class="computeroutput">Database "demo" will be permanently deleted.
