     <listitem>
      <para>
       Never issue a password prompt.  If the server requires password
       authentication and a password is not available by other means such as
       a <filename>.pgpass</filename> 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.

       Force <application>pg_amcheck</application> to prompt for a password
       before connecting to a database.
      </para>
      <para>
       This option is never essential, since
       <application>pg_amcheck</application> will automatically prompt for a
       password if the server demands password authentication.  However,
       <application>pg_amcheck</application> will waste a connection attempt
       finding out that the server wants a password.  In some cases it is
       worth typing <option>-W</option> to avoid the extra connection attempt.

       Specifies a database or

       used to discover the list of databases to be checked. If neither
       <option>--all</option> nor any option including a database pattern is
       used, no such connection is required and this option does nothing.
       Otherwise, any connection string parameters other than
       the database name which are included in the value for this option
       will also be used when connecting to the databases
       being checked. If this option is omitted, the default is
       <literal>postgres</literal> or, if that fails,
       <literal>template1</literal>.
