<title>Semi-internal Options</title>
<para>
Two additional command line options are available for debugging
problems that cause a server process to die abnormally. The
ordinary strategy in this situation is to notify all other server
processes that they must terminate and then reinitialize the
shared memory and semaphores. This is because an errant server
process could have corrupted some shared state before terminating.
These options select alternative behaviors of the
<command>postmaster</command> in this situation.
<emphasis>Neither option is intended for use in ordinary
operation.</emphasis>
There are several other options that may be specified, used
mainly for debugging purposes and in some cases to assist with
recovery of severely damaged databases. There should be no reason
to use them in a production database setup. These are listed
here only for the use by <productname>PostgreSQL</productname>
system developers. <emphasis>Use of any of these options is
highly discouraged.</emphasis> Furthermore, any of these options
may disappear or change in a future release without notice.
