No attribute table in a vector means no need for a db connection, (is it our
case?) but if you got 'null' atts for some cats I think you should not
delete those records at all.

Null values in a db table won't do you no harm and you will spent only few
bytes for the primary key storage ;)
of course you won't see the warnings
