agreed. as soon as i get the 8.03 setup, i'm going to
uninstall the 7.4.x version from my dev box and
upgrade it to 8.03.
any db work on my 7.3.x webhost will be pretty minimal
from that time forward. if i do anything serious, i
will most likely change webhosts to one that keeps up
to date with pgsql.

Chris, i may well end up following your very thorough
process... but i'm going to try creating the new prod
cb structure using my current dev table structure and
then i'm going to try and pull data from the old prod
box and try and restore it to the new db.
i'm crossing my fingers... if that doesn't work, i'll
follow your cookbook instructions. fingers still
