Hi All,
This might be a noob question, but I wasn't able to to find the answer
combing through the docs and google search. Given the following

class A(Base):

id = Column(Integer, primary_key=True)
class B(Base):

I understand I can disable RETURNING for an engine with

Is there a way to do this for certain primary key columns only, but
not disabled engine-wide?

Just a note, your suggestion works for me but will fail for any
unsigned columns.

i have a few polymorphic tables, and i want to sort by a column in one of

i have tables a,b,c,d, with relationship a to b, b to c, c to d.
a to b is one-to-many b to c and c to d are one-to-one, but polymorphic.

I'll look into the new code. It does look simpler. I tried using the
