currently SMBTAD's data logging is undergoing massive changes and every new version has different DB structure (or even backend). Starting with 1.2.6 database and smbtad versions were integrated to database structure. Currently the only way to upgrade DB structure is to use smbtaquery with special params. Unfortunately smbtaquery is part of smbtatools - a separate package. To make transitions simpler for users, I suggest moving database upgrade part from smbtaquery to smbtad. That way not only we do not require dependency on separate package to perform DB upgrade, but also we're able to upgrade DB structure without user's intervention during package update.
This will be the case with 1.2.7
There are no database additions planned for 1.2.7, but however, if a change in the db format will come, we will change it in smbtad. Therefore I'll closing this as fixed.
