Thank you kevin , i've worked a lot over PG and this tecnique is
consolidated in our model.. but here the problem is that the column
is a simply <column_name> INTEGER NOT NULL references
<other_table>(id) and i cannot understand why sqlalchemy whant to use it
as a
<column_name> SERIAL
Thank you
Glauco
