The object which describes a single file contains either a
<code class="literal">Path</code> key or an <code class="literal">Encoded-Path</code> key.
Normally, the <code class="literal">Path</code> key will be present. The
associated string value is the path of the file relative to the root
of the backup directory. Files located in a user-defined tablespace
will have paths whose first two components are <code class="filename">pg_tblspc</code> and the OID
of the tablespace. If the path is not a string that is legal in UTF-8,
or if the user requests that encoded paths be used for all files, then
the <code class="literal">Encoded-Path</code> key will be present instead. This
stores the same data, but it is encoded as a string of hexadecimal
digits. Each pair of hexadecimal digits in the string represents a
single octet.
</p><p>
The following two keys are always present:
</p><div class="variablelist"><dl class="variablelist"><dt><span class="term"><code class="literal">Size</code></span></dt><dd><p>
The expected size of this file, as an integer.
</p></dd><dt><span class="term"><code class="literal">Last-Modified</code></span></dt><dd><p>
The last modification time of the file as reported by the server at
the time of the backup. Unlike the other fields stored in the backup,
this field is not used by <a class="xref" href="app-pgverifybackup.html" title="pg_verifybackup"><span class="refentrytitle"><span class="application">pg_verifybackup</span></span></a>.
It is included only for informational purposes.
</p></dd></dl></div><p>
If the backup was taken with file checksums enabled, the following
keys will be present:
</p><div class="variablelist"><dl class="variablelist"><dt><span class="term"><code class="literal">Checksum-Algorithm</code></span></dt><dd><p>
The checksum algorithm used to compute a checksum for this file.
Currently, this will be the same for every file in the backup
manifest, but this may change in future releases. At present, the
supported checksum algorithms are <code class="literal">CRC32C</code>,
<code class="literal">SHA224</code>,
<code class="literal">SHA256</code>,
<code class="literal">SHA384</code>, and
<code class="literal">SHA512</code>.
</p></dd><dt><span class="term"><code class="literal">Checksum</code></span></dt><dd><p>
The checksum computed for this file, stored as a series of
hexadecimal characters, two for each byte of the checksum.
