*
* The pg_subtrans manager is a pg_clog-like manager that stores the parent
* transaction Id for each transaction. It is a fundamental part of the
* nested transactions implementation. A main transaction has a parent
* nested transactions implementation. A main transaction has a parent
* of InvalidTransactionId, and each subtransaction has its immediate parent.
* The tree can easily be walked from child to parent, but not in the
* opposite direction.
