Postgres transaction isolation level

Hi, Probably I’m missing something but I couldn’t find a way to specify transaction isolation level for Postgres (default to Read committed which is not sufficient for my use case - in which Repeatable read is needed).

Any way to workaround it (without changing postgres config or manually open transaction)?

Thanks a lot!

OK. Thanks again.

In case someone else will encounter this thread - another possible option (which i didn’t try) is to use raw SET TRANSACTION statement which should be ran before any other query in the transaction.

@contextmanager
def isolation(level):
    conn = db.connection()
    orig = conn.isolation_level
    conn.set_isolation_level(level)
    try:
        with db.atomic() as txn:
            yield txn
    finally:
        conn.set_isolation_level(orig)

Something like this?
