+ <span class="application">dropuser</span> removes an existing
+ <span class="productname">PostgreSQL</span> user.
+ Only superusers and users with the <code class="literal">CREATEROLE</code> privilege can
+ remove <span class="productname">PostgreSQL</span> users. (To remove a
+ superuser, you must yourself be a superuser.)
+ </p><p>
+ <span class="application">dropuser</span> is a wrapper around the
+ <acronym class="acronym">SQL</acronym> command <a class="link" href="sql-droprole.html" title="DROP ROLE"><code class="command">DROP ROLE</code></a>.
+ There is no effective difference between dropping users via
+ this utility and via other methods for accessing the server.
+ </p></div><div class="refsect1" id="id-1.9.4.7.6"><h2>Options</h2><p>
+ <span class="application">dropuser</span> accepts the following command-line arguments:
+
+ </p><div class="variablelist"><dl class="variablelist"><dt><span class="term"><em class="replaceable"><code>username</code></em></span></dt><dd><p>
+ Specifies the name of the <span class="productname">PostgreSQL</span> user to be removed.
+ You will be prompted for a name if none is specified on the command
+ line and the <code class="option">-i</code>/<code class="option">--interactive</code> option
+ is used.
+ </p></dd><dt><span class="term"><code class="option">-e</code><br /></span><span class="term"><code class="option">--echo</code></span></dt><dd><p>

+ <span class="application">dropuser</span> also accepts the following

+ as the directory for the Unix domain socket.
+ </p></dd><dt><span class="term"><code class="option">-p <em class="replaceable"><code>port</code></em></code><br /></span><span class="term"><code class="option">--port=<em class="replaceable"><code>port</code></em></code></span></dt><dd><p>
+ Specifies the TCP port or local Unix domain socket file

+ Never issue a password prompt. If the server requires

+ </p></dd><dt><span class="term"><code class="option">-W</code><br /></span><span class="term"><code class="option">--password</code></span></dt><dd><p>
+ Force <span class="application">dropuser</span> to prompt for a

+ </p><p>
+ This option is never essential, since
+ <span class="application">dropuser</span> will automatically prompt
+ for a password if the server demands password authentication.
+ However, <span class="application">dropuser</span> will waste a
+ connection attempt finding out that the server wants a password.
+ In some cases it is worth typing <code class="option">-W</code> to avoid the extra
+ connection attempt.
