+				<p>Provides a field to store bytes as PostgreSQL large objects.
+					PostgreSQL offers support for large objects, which provide
+					stream-style access to user data that is stored in a special
+					large-object structure. They are useful with data values too large
+					to be manipulated conveniently as a whole.</p>
+				<h5 style="padding-top: 10px;">Psycopg2 for Python</h5>
+				<p>
+					Psycopg allows access to the large object using the
+					<code>lobject</code>
+					class. Objects are generated using the
+					<code>connection.lobject()</code>
+					factory method. Data can be retrieved either as bytes or as Unicode
+					strings.
+				</p>
+				<p>
+					Psycopg large object support efficient import/export with file
+					system files using the
+					<code>lo_import()</code>
+					and
+					<code>lo_export()</code>
+					libpq functions.
+				</p>
+				<p>Changed in version 2.6: added support for large objects
+					greated than 2GB. Note that the support is enabled only if all the
+					following conditions are verified:</p>
+				<ul>
+					<li>the Python build is 64 bits;</li>
+					<li>the extension was built against at least libpq 9.3;</li>
+					<li>the server version is at least PostgreSQL 9.3
+						(server_version must be >= 90300).</li>
+				</ul>
+				<p>
+					If Psycopg was built with 64 bits large objects support (i.e. the
+					first two contidions above are verified), the
+					<code>psycopg2.__version__</code>
+					constant will contain the lo64 flag. If any of the contition is not
+					met several lobject methods will fail if the arguments exceed 2GB.
