   semaphore sets owned by the current user.  It is intended to be

> server (<A

>).  Note that immediately restarting the
   server will also clean up shared memory and semaphores, so this
   command is of little real utility.
  </P
><P
>   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.

>Notes</H2
><P
>   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 <TT
CLASS="COMMAND"
>postgres</TT
> can now clean up by
   itself, it is unlikely that <TT
CLASS="COMMAND"
>ipcclean</TT
> will be
   improved upon in the future.
  </P
><P
>   The script makes assumptions about the output format of the
   <TT
CLASS="COMMAND"
>ipcs</TT
>
   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.
