There is no effective difference between reindexing databases via
this utility and via other methods for accessing the server.

<listitem>
<para>
Specifies the name of the database to be reindexed.
If this is not specified and <option>-a</option> (or
<option>--all</option>) is not used, the database name is read
from the environment variable <envar>PGDATABASE</envar>. If
that is not set, the user name specified for the connection is

<varlistentry>
<term><option>-p <replaceable class="parameter">port</replaceable></></term>
<term><option>--port <replaceable class="parameter">port</replaceable></></term>
