<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.
</para>

<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.
