I start with a database empty.
db = DAL('postgres://usr:psw@localhost/sisteq2', pool_size=10,
check_reserved=['all'], *migrate=True, fake_migrate_all=False*)
my model:

Ok. First execution model, creates the table in the database. So far so
normal. (When I say "run the model" I mean to make a request from the

Second execution model. All right, the field is removed from the table.
Third execution. *Fails*
ProgrammingError: column "f2" of relation "mi_tabla" does not exist
Is everything I did. DAL continued as it was originally:
db = DAL('postgres://usr:psw@localhost/sisteq2', pool_size=10,
check_reserved=['all'], *migrate=True, fake_migrate_all=False*)
