From 9ec6a9b8e336caf6ef79451f1154f40fc5e771a1 Mon Sep 17 00:00:00 2001
From: Robert Leftwich <rtl@pobox.com>
Date: Thu, 1 Dec 2005 12:51:38 +0000
Subject: Added float type to support real/double precision/float8/etc sql data
 types. Added columns.py as unit test. Modified sqlite.py, postgres.py and
 mysql.py to use the new type where appropriate (note -Oracle is unchanged at
 present).
