+ <para>
+ <filename>basic_archive</filename> is an example of an archive module. This
+ module copies completed WAL segment files to the specified directory. This
+ may not be especially useful, but it can serve as a starting point for
+ developing your own archive module. For more information about archive
+ modules, see <xref linkend="archive-modules"/>.
+ </para>
+
+ <para>
+ In order to function, this module must be loaded via
+ <xref linkend="guc-archive-library"/>, and <xref linkend="guc-archive-mode"/>
+ must be enabled.

+ The directory where the server should copy WAL segment files. This
+ directory must already exist. The default is an empty string, which
+ effectively halts WAL archiving, but if <xref linkend="guc-archive-mode"/>
+ is enabled, the server will accumulate WAL segment files in the
+ expectation that a value will soon be provided.

+
+ <para>
+ Server crashes may leave temporary files with the prefix
+ <filename>archtemp</filename> in the archive directory. It is recommended to
+ delete such files before restarting the server after a crash. It is safe to
+ remove such files while the server is running as long as they are unrelated
+ to any archiving still in progress, but users should use extra caution when
+ doing so.
