Description

My ./bin/gmg dbupdate command went bad, and thus broke the instance.

When trying to execute a new dbupdate, I've come across this:

I suppose the SQL statment from sqlalchemy should have a "IF_NOT_EXISTS" right after the "CREATE TABLE", but it doesn't.

My db remains broken, and thus the instance.
