From 3273c981f8d370ce6ccc6cbd8a20fea4f9d64de0 Mon Sep 17 00:00:00 2001
From: Adrian Holovaty <adrian@holovaty.com>
Date: Sun, 13 Nov 2005 05:11:41 +0000
Subject: [PATCH] Moved db.quote_name from a model-level function to a method
 of DatabaseWrapper for all database backends, so quote_name will be
 accessible in a 'from django.core.db import db' context
