Access the state of a transaction given the NpgsqlConnection

Is there any way to get any indicator to an ongoing transaction given a NpgsqlConnection instance such as Connector.InTransaction? As an alternative would it at least somehow be possible to access the state of a transaction itself, such as NpgsqlTransaction.Diposed?

I guess we could expose the transaction status indicator, just as the protocol delivers it to us in the ReadyForQuery message. I wouldn’t attempt to expose NpgsqlTransaction - it may not exist (if the transaction was created with raw SQL), and it really is the caller’s responsibility to track that instance.

If we do decide to do this, I think we should expose the full three values, not just a bool (so idle, in a transaction, in a failed transaction). Knowing whether the connection is in a failed transaction seems just as useful… Note that our internal enum used for representing this is probably not suitable, since it also contains an internal-only Pending value, so we may need another enum…

But I think all this should go into the backlog - we have more urgent things to do… @TwentyFourMinutes if you’re going down the wrapping route, I’d go all the way like EF Core does and wrap NpgsqlTransaction.

Not sure if it’s “wrong”, but a simple true/false flag is insufficient to represent the three-value state.
