Background: Using core we have tables defined in a few separate files.
Goal: To have column defaults be selectables which reference other tables
while avoiding circular imports. To avoid circular imports I cannot always
build the selects at import time, they have to be generated inside a
functio

Just core, you can some_table.append_column(Column(... whatever...)) at
any time.The only "event" I can think of are the DDL attachment events:
from sqlalchemy import *
from sqlalchemy import event
m = MetaData()
table_a = Table(
'a', m,
Column('id', Integer)
)
@event.listens_fo
Awesome, both look good, will try them out. Thanks for the quick reply.

We're just using core, is there some equivalent?
