AlloyDB- CREATE DATABASE can not be run in a transaction block

[Sumit Desai]

Since AlloyDB does not support creating a database using terraform yet, I am trying to create it using Alembic and sqlAlchemy. I am using postgresql+psycopg2 as the driver.My code looks similar to the only answer on here.

from sqlalchemy import create_engine
dburl = "postgresql+psycopg2://user:pswd@myip:5432/postgres/"
engine = create_engine(dburl)
conn = engine.connect()

con.rollback()  # Make sure we're not in a transaction
con.autocommit = True  # Turn on autocommit

conn.execute("CREATE DATABASE qux")
 
con.autocommit = False  # Turn autocommit back off again

However, I am getting an error sqlalchemy.exc.InternalError: (psycopg2.errors.ActiveSqlTransaction) CREATE DATABASE cannot run inside a transaction block. Is this expected when I am turning on auto-commit and rollick back transaction?

Additional metadata-

• OS: Ubuntu 22.04
• Psycopg version: 2.9.9
• Python version: 3.10
• PostgreSQL version: AlloyDB
• pip version- 3

psycopg work no problem with CREATE DATABASE. Please get in touch with SQLAlchemy to figure out why it doesn't.
