<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>
Echo the commands that <span class="application">dropuser</span> generates
and sends to the server.
</p></dd><dt><span class="term"><code class="option">-i</code><br /></span><span class="term"><code class="option">--interactive</code></span></dt><dd><p>
Prompt for confirmation before actually removing the user, and prompt
for the user name if none is specified on the command line.
</p></dd><dt><span class="term"><code class="option">-V</code><br /></span><span class="term"><code class="option">--version</code></span></dt><dd><p>
Print the <span class="application">dropuser</span> version and exit.
</p></dd><dt><span class="term"><code class="option">--if-exists</code></span></dt><dd><p>
Do not throw an error if the user does not exist. A notice is
issued in this case.
</p></dd><dt><span class="term"><code class="option">-?</code><br /></span><span class="term"><code class="option">--help</code></span></dt><dd><p>
Show help about <span class="application">dropuser</span> command line
arguments, and exit.
</p></dd></dl></div><p>
</p><p>
<span class="application">dropuser</span> also accepts the following
command-line arguments for connection parameters:
</p><div class="variablelist"><dl class="variablelist"><dt><span class="term"><code class="option">-h <em class="replaceable"><code>host</code></em></code><br /></span><span class="term"><code class="option">--host=<em class="replaceable"><code>host</code></em></code></span></dt><dd><p>
Specifies the host name of the machine on which the
server
is running. If the value begins with a slash, it is used
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
extension on which the server
is listening for connections.
</p></dd><dt><span class="term"><code class="option">-U <em class="replaceable"><code>username</code></em></code><br /></span><span class="term"><code class="option">--username=<em class="replaceable"><code>username</code></em></code></span></dt><dd><p>
User name to connect as (not the user name to drop).
</p></dd><dt><span class="term"><code class="option">-w</code><br /></span><span class="term"><code class="option">--no-password</code></span></dt><dd><p>
Never issue a password prompt. If the server requires
password authentication and a password is not available by
other means such as a <code class="filename">.pgpass</code> file, the
connection attempt will fail. This option can be useful in
batch jobs and scripts where no user is present to enter a
password.
</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
password before connecting to a database.
</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.
</p></dd></dl></div><p>
</p></div><div class="refsect1" id="id-1.9.4.7.7"><h2>Environment</h2><div class="variablelist"><dl class="variablelist"><dt><span class="term"><code class="envar">PGHOST</code><br /></span><span class="term"><code class="envar">PGPORT</code><br /></span><span class="term"><code class="envar">PGUSER</code></span></dt><dd><p>
Default connection parameters
</p></dd><dt><span class="term"><code class="envar">PG_COLOR</code></span></dt><dd><p>
Specifies whether to use color in diagnostic messages. Possible values
are <code class="literal">always</code>, <code class="literal">auto</code> and
<code class="literal">never</code>.
</p></dd></dl></div><p>
This utility, like most other <span class="productname">PostgreSQL</span> utilities,
also uses the environment variables supported by <span class="application">libpq</span>
(see <a class="xref" href="libpq-envars.html" title="34.15. Environment Variables">Section 34.15</a>).
</p></div><div class="refsect1" id="id-1.9.4.7.8"><h2>Diagnostics</h2><p>
In case of difficulty, see <a class="xref" href="sql-droprole.html" title="DROP ROLE"><span class="refentrytitle">DROP ROLE</span></a>
and <a class="xref" href="app-psql.html" title="psql"><span class="refentrytitle"><span class="application">psql</span></span></a> for
discussions of potential problems and error messages.
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></div><div class="refsect1" id="id-1.9.4.7.9"><h2>Examples</h2><p>
To remove user <code class="literal">joe</code> from the default database
server:
</p><pre class="screen">
<code class="prompt">$ </code><strong class="userinput"><code>dropuser joe</code></strong>
</pre><p>
</p><p>
To remove user <code class="literal">joe</code> using the server on host
<code class="literal">eden</code>, port 5000, with verification and a peek at the underlying
command:
</p><pre class="screen">
<code class="prompt">$ </code><strong class="userinput"><code>dropuser -p 5000 -h eden -i -e joe</code></strong>
<code class="computeroutput">Role "joe" will be permanently removed.
Are you sure? (y/n) </code><strong class="userinput"><code>y</code></strong>
<code class="computeroutput">DROP ROLE joe;</code>
