[Postgres-xl-general] Running machine local, internode traffic over Unix domain socket

Hi,

with cross-node joins, a lot of data might need to be shuffled between 
the nodes.

On a single SMP box, this boils down to loopback TCP.

I'd like to reduce the overhead and shuffle every inter-node 
communication over Unix domain sockets:

datanodes <-> datanodes
datanodes <-> coordinator

Is that possible? Using the pgxc_ctl?

Thanks,
/Tobias
