How to make a bigserial field ?

Postgresql supports BIGSERIAL but how to create that in databases postgresql

[encryptblockr]

by using BigInteger

from sqlalchemy import BigInteger

metadata = MetaData()

users = Table(
    "users", metadata,
    Column("id", BigInteger, primary_key=True),
)

What if I don't want to use it without sqlalchemy. Like writing queries

id BIGSERIAL PRIMARY KEY

Can I do this?
