(Stateless and Distributed) Transaction in Event Driven Architecture

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 ?
