OK, so it looks to me like we lazily initialize the database in tosa (I'm going by what I see in the code, this might be wrong). I'm looking at the latest version of Tosa, so this API may be totally different with what you've got, but from what I see, you may want to try this:
DBLocator.Database.DBUpgrader.recreateTables()
I'll investigate more tomorrow.
Cheers,
