Hello Folks,


I am aiming to use PG in an application which has distributed event driven architecture. (CSP/Actor based)

I wanted to know if it possible to carry out transactions across distributed process/machines using different PG connections.

1.  Machine A starts transaction with connection1
2.  Machine A delegates request to Machine B
3.  Machine B opens connection2
4.  Machine B does some updates 
5.  Machine B delegates request to Machine C
6.  Machine C opens connection3
7.  Machine C does some updates
8.  Machine C commits transaction


Now in order to make it happen, I need to issue some sort of transaction_token to PG when transaction starts at Machine A and forwards it to other machines so that transaction context is not lost while making select/update/insert/delete calls to PG ?

Is it possible through any native PG features or any plugin ? Is it too much to ask for ?
