  22.    command <a class="xref" href="sql-reindex.html" title="REINDEX"><span class="refentrytitle">REINDEX</span></a>.

  23.    There is no effective difference between reindexing databases via

  24.    this utility and via other methods for accessing the server.

  25.   </p></div><div class="refsect1" id="id-1.9.4.19.6"><h2>Options</h2><p>

  26.     <span class="application">reindexdb</span> accepts the following command-line arguments:

  31.         Use the <code class="literal">CONCURRENTLY</code> option.  See

  32.         <a class="xref" href="sql-reindex.html" title="REINDEX"><span class="refentrytitle">REINDEX</span></a>, where all the caveats of this option

  33.         are explained in detail.

  35.         Specifies the name of the database to be reindexed.

  36.         If this is not specified and <code class="option">-a</code> (or

  37.         <code class="option">--all</code>) is not used, the database name is read

  38.         from the environment variable <code class="envar">PGDATABASE</code>.  If

  70.     <span class="application">reindexdb</span> also accepts

  74.         Specifies the host name of the machine on which the server is

  75.         running.  If the value begins with a slash, it is used as the

  76.         directory for the Unix domain socket.

  77.        </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>

  78.         Specifies the TCP port or local Unix domain socket file

  79.         extension on which the server

  80.         is listening for connections.

  81.        </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>

  83.        </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>

  84.         Never issue a password prompt.  If the server requires

  85.         password authentication and a password is not available by

  86.         other means such as a <code class="filename">.pgpass</code> file, the

  87.         connection attempt will fail.  This option can be useful in

  88.         batch jobs and scripts where no user is present to enter a

  89.         password.

  90.        </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>

  91.         Force <span class="application">reindexdb</span> to prompt for a

  92.         password before connecting to a database.

  93.        </p><p>

  94.         This option is never essential, since

  95.         <span class="application">reindexdb</span> will automatically prompt

  96.         for a password if the server demands password authentication.

  97.         However, <span class="application">reindexdb</span> will waste a

  98.         connection attempt finding out that the server wants a password.

  99.         In some cases it is worth typing <code class="option">-W</code> to avoid the extra

  100.         connection attempt.

  101.        </p></dd><dt><span class="term"><code class="option">--maintenance-db=<em class="replaceable"><code>dbname</code></em></code></span></dt><dd><p>

  102.          Specifies the name of the database to connect to discover what other

  103.          databases should be reindexed. If not specified, the

  104.          <code class="literal">postgres</code> database will be used,

  105.          and if that does not exist, <code class="literal">template1</code> will be used.

  114.    This utility, like most other <span class="productname">PostgreSQL</span> utilities,

  115.    also uses the environment variables supported by <span class="application">libpq</span>

  116.    (see <a class="xref" href="libpq-envars.html" title="33.14. Environment Variables">Section 33.14</a>).

  119.    and <a class="xref" href="app-psql.html" title="psql"><span class="refentrytitle"><span class="application">psql</span></span></a> for

  120.    discussions of potential problems and error messages.

  121.    The database server must be running at the

  122.    targeted host.  Also, any default connection settings and environment

  123.    variables used by the <span class="application">libpq</span> front-end

  124.    library will apply.

  125.   </p></div><div class="refsect1" id="id-1.9.4.19.9"><h2>Notes</h2><p>

  126.    <span class="application">reindexdb</span> might need to connect several

  127.    times to the <span class="productname">PostgreSQL</span> server, asking

  128.    for a password each time. It is convenient to have a

  129.    <code class="filename">~/.pgpass</code> file in such cases. See <a class="xref" href="libpq-pgpass.html" title="33.15. The Password File">Section 33.15</a> for more information.
