transaction_guard: Ability to specify transaction type

[trevornagy]

By default the transaction_guard API calls: begin_transaction.

Would it be possible to add to the transaction_guard API a way to specify the type of transaction? For example, what if I want to use transaction_guard + begin_immediate_transaction / transaction_guard + begin_exclusive_transaction?

Is this possible?

Thanks!

It is not possible but we can think about it. Either to add more functions like immediate_transaction_guard or adding enum argument to transaction_guard
