Autonomous Transaction Storage:

As for main transaction, structure PGXACT is used to store main transactions, which are created in shared memory of size:

                        (Number of process)*sizeof(struct PGXACT)

Similarly a new structure will be defined to store autonomous transaction:

Struct PGAutonomousXACT


I already proposed exactly this design two years ago and it was rejected at the PgCon hackers meeting.

I have a better design worked out now and will likely be working on it for 9.5
