<application>pg_restore</application> is a utility for restoring a
<productname>Postgres</productname> database dumped by <application>pg_dump</application>
from any one of the non-plain-text output formats.
</para>
<para>
The archive files, new with this relase, contain enough information for
<application>pg_restore</application> to rebuild the database, but also allow
<application>pg_restore</application> to be selective about what is restored,
or even to reorder the items prior to being restored. The archive files should
also be portable across architectures. <application>pg_dump</application> will
produce the queries necessary to re-generate all user-defined types, functions,
tables, indices, aggregates, and operators. In addition, all the data is copied
out (in text format for scripts) so that it can be readily copied in again.

</para>
<para>
<application>pg_restore</application> reads the archive file and outputs the appropriate
SQL in the required order based on the command parameters. Obviously, it can not restore
information that is not present in the dump file; so if the dump is made using the
'dump data as inserts' option, <application>pg_restore</application> will not be able to
load the data using <command>COPY</command> statements.
</para>
<para>
The most flexible output file format is the new 'custom' format (-Fc). It allows for
selection and reordering of all archived items, and is compressed by default. The TAR
format (-Ft) is not compressed and it is not possible to reorder
data load, but it is otherwise quite flexible.
</para>
<para>
To reorder the items, it is first necessary to dump the contents of the archive:
<programlisting>
$ pg_restore acrhive.file --list > archive.lis
</programlisting>
This file consists of a header and one line for each item, eg.
