-STEPS TO UPGRADE YOUR INSTALL:
-If you need to upgrade the geocoder/tiger loader from a pre-release
-2.0.0 install -- run the upgrade_geocoder.sh or upgrade_geocoder.bat
-script.
-
-CAUTION: The upgrade script will drop any table columns that have a
-norm_addy type for a column type.  This is rare if ever done so you
-should be fine.  We plan to fix this later. It will also drop any
-customizations you have made to the tiger_loader configuration tables.
-To prevent this, you can remark out the install loader part.  This we
-plan to remedy in the future.
-
-It will also install any missing indexes that are deemed needed by
-queries.
-
-It will fail on some steps such as addition of new columns 
-to lookup tables if they already exist in your intall.  
-These errors can be safely ignored.
