That is correct. The Postgres backend handles conversion of values
going into the DB with the following snippet from
PostgresConnection.to_database():
def to_database(self, params):
for param in params:
...
elif isinstance(param, str):
yield psycopg2.Binary(param)
If you need to do any fixups on the values returned by the database
adapter, you can use a subclass of storm.database.Result and override
from_database() like the mysql backend does.
