I'm already doing that, but without using adbapi. When I started this project 
adbapi was no choice and now it's simply not an option to rewrite a lot of 
code to something I expect to be even slower than my code. I use a very lean 
row class based on slots and a db interface that handles the schema itself 
without me supplying it. This certainly is database dependant but I can 
afford to support postgres only.
