How to check for pending operations in a PostgreSQL transaction

Question

I have a session (SQLAlchemy) on PostgreSQL, with an active uncommitted transaction. I have just passed the session to some call tree that may or may not have issued SQL

Answer 1

No, not from the database level, really. Perhaps you can add some tracing at the sqlalchemy level to track it?

Also, how do you define a no-op? What if you updated a value to the same value it had before, is that a no-op or not? From the databases perspective, if it had one, it would not be a no-op. But from the application perspective, it probably would.
