-  <title>Description</title>
-  <para>
-   <command>ipcclean</command> removes all shared memory segments and
-   semaphore sets owned by the current user.  It is intended to be
-   used for cleaning up after a crashed
-   <productname>PostgreSQL</productname> server (<xref
-   linkend="app-postgres">).  Note that immediately restarting the
-   server will also clean up shared memory and semaphores, so this
-   command is of little real utility.
-  </para>
-
-  <para>
-   Only the database administrator should execute this program as it
-   can cause bizarre behavior (i.e., crashes) if run during multiuser
-   execution.  If this command is executed while a server is running,
-   the shared memory and semaphores allocated by that server will be
-   deleted, which would have rather severe consequences for that
-   server.

-  <title>Notes</title>
-
-  <para>
-   This script is a hack, but in the many years since it was written,
-   no one has come up with an equally effective and portable solution.
-   Since <command>postgres</command> can now clean up by
-   itself, it is unlikely that <command>ipcclean</command> will be
-   improved upon in the future.
-  </para>
-
-  <para>
-   The script makes assumptions about the output format of the
-   <command>ipcs</command>
-   utility which might not be true across different operating systems.
-   Therefore, it might not work on your particular OS.  It's wise to
-   look at the script before trying it.
