postgresql protocol v3

So I've been trying to add blob and prepared-query support to the 
various flavors of the postgresql drivers. I've got the libpq version 
working to a first approximation, but I'd like to get the 
postgresql-socket stuff working too. Unfortunately, in order to do the 
prepared query stuff I need protocol v3. I'm assuming there are some 
folks who would like to continue to use v2 for talking to postgres 6 
databases (or whenever protocol v3 appeared). Any objections to adding 
a postgresql-socket-v3 module to clsql? It seems a little silly to have 
three separate modules for talking to postgresql databases, but I'm not 
sure there's a better alternative. Suggestions? Comments?

Thanks,

Cyrus
