capabilities of specifying time zones as intervals per SQL9x. Put refentrytitle contents on the same line as the tag. Otherwise, leading whitespace is propagated into the product, which (at least) messes up the ToC layout. Remove (some) docinfo tags containing dates. Best to omit if the dates are not accurate; maybe use CVS dates instead or leave them out.

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

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
|
|
<application>postmaster</application> is running, the shared memory
|
|
and semaphores allocated by the
|
|
<application>postmaster</application> will be deleted. This will
|
|
result in a general failure of the backend servers started by that
|
|
<application>postmaster</application>.

<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 the <application>postmaster</application> 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 assumption about the format of output of the
|
|
<application>ipcs</application>
|
|
utility which may not be true across different operating systems.
|
|
Therefore, it may not work on your particular OS.
