@staticmethod<EOL><INDENT>def _serialize_cell(cell, conn):<DEDENT>
return cell<EOL>
Postgresql will adapt all arguments to the execute() method internally,
hence we return cell without any conversion.

See http://initd.org/psycopg/docs/advanced.html#adapting-new-types for
more information.

:param cell: The cell to insert into the table
:type cell: object
