So build-depending on libdb-dev should mean you wouldn't need to change
the b-d ever again unless there's an incompatible API change that isn't
handled by the upstream code.  Furthermore, it would be possible to
switch to a newer version with just a binNMU.

Given your transient data description, I doubt there will be any trouble
with you always keeping up with what is deemed the "current" version.
