<function>pg_stat_file()</> returns a record containing the file
length, last accessed timestamp, last modified timestamp,
creation timestamp, and a boolean indicating if it is a directory.
Typical usages include:
size, last accessed timestamp, last modified timestamp,
last file status change timestamp (Unix platforms only),
file creation timestamp (Win32 only), and a boolean indicating
if it is a directory. Typical usages include:
<programlisting>
SELECT * FROM pg_stat_file('filename');
SELECT (pg_stat_file('filename')).mtime;
SELECT (pg_stat_file('filename')).modification;
</programlisting>
