I know about PostgresXC, but I thought it is distributed database (similar
to shards of mongoDB). [Though if I am correct there could be tables which
are shared across different nodes, but that is not the best way of
utilizing features of PostgresXC] I think it is not apt to call it
"synchronous" (since there is no replication happening).
