receive and transmit streaming replication at same time

Hello List,

a lot of recherche and no answer so far. So my question to you:

Is it possible to set up ONE PostgreSQL 9 to serve as a streaming
replication provider (Master) and receiver (client) at the same time?

Can i configure both to
* accept 'insert into ...' & stream that changes out (usual master)
AND
* catch streaming from another streaming ?

My application:
* Two servers acquire measurements at the same time into one table.
* No risk of conflicts!
* No need of standby skills (for now).


Thanks,
Bastian
