PG's ENUM does work that way, below the same type is shared:

from sqlalchemy import Column
from sqlalchemy import create_engine
from sqlalchemy import Integer
from sqlalchemy.ext.declarative import declarative_base
from sqlalchemy.orm import Session
from sqlalchemy.dialects import postgresql

Base = declarative_base()

State = postgresql.ENUM("AK", "AL", "CO", "NY", name="states")

class A(Base):
   __tablename__ = 'a'

   id = Column(Integer, primary_key=True)
   data = Column(State)


class B(Base):
   __tablename__ = 'b'
   id = Column(Integer, primary_key=True)
   data = Column(State)

  Thanks, Mike.

Best regards,
