a. Installed in Production?

b. Tested with DAW drivers?

Just looking at options, and while PSQL11 has been very good for us I note pricing on MSSQL and Pervasive /Actian Zen15 are similar at the moment. I believe our POS users wouldn't like the observable downgrade in speed posting transactions into MSSQL but OTOH moving our analytics table to MSSQL Express is very doable. Hybrid is da ting, ya no?
