GCP CloudSQL Connector with asyncpg Pool

[d1manson]

Not sure if i'm better asking this on the cloud sql python connector repo or here, but I'm trying to understand how to effectively call asyncpg.create_pool(...) but make it work with the cloudsql connector.

I can create a single asyncpg-style connection using this:

from google.cloud.sql.connector import Connector

async def init():  
    connector = Connector(enable_iam_auth=True, loop=asyncio.get_event_loop())
    conn =  await connector.connect_async(
                instance_connection_string="my-project:region:db-name",
                driver="asyncpg",
                db="postgres",
                user="something@my-project.iam.gserviceaccount.com")
    # do init stuff...
    await conn.set_type_codec("json", encoder=json.dumps, decoder=json.loads, schema="pg_catalog")
    return conn

but i'm not sure how to do a complete drop in replacement for async.create_pool, which is what we have in the existing codebase; I'm hoping to retain the pool object as is so that the rest of the codebase doesn't need to be modified in light of switching to CloudSQL.

Thanks!
