Well, for me it works fine this way. Also, this is only the default
behavior. If you don't provide a connection spec to defdao (macro
creating a subclass of dao with the metaclass set do db-class), then
no SQL queries will be executed (I use this feature for making
fixtures and base classes on the Lisp side that shouldn't have any
effect on the Postgres side).

Do you think this is enough for saving that ton of headaches? :) If it
is not, please don't hesitate to give examples of problems that may
arise, and I will try to do something about them.

Cheers,
