Ok, found the cause. CommandStatus in sqlobject/manager/command.py list
columns using columnsFromScheme(), a kind of forced fromDatabase=True. And
most connection classes don't recognize size/precision in DecimalCol'umns.
In this particular case it would be enough, I think, to extend
columnsFromScheme to pass None's as size/precision. I will do some
experiments before committing the hack.
