    <para>
     In <option>start</option> mode, a new server is launched.  The
!    server is started in the background, and standard input is attached
!    to <filename>/dev/null</filename> (or <literal>nul</> on Windows).
!    On Unix-like systems, by default, the server's standard output and
!    standard error are send to <application>pg_ctl</application>'s
!    standard output (not standard error).  The standard output of
!    <application>pg_ctl</application> should then be redirected to a

!    will write its output to the controlling terminal (from the
!    background) and will not leave the shell's process group.  On
!    Windows, by default the server's standard output and standard error
!    are sent to the terminal.  These default  behaviors can be changed
!    by using <option>-l</option> to append server output to a log file.
