Hello.

Is there a way to compress the traffic between master and slave during the replication?.. The streaming gzip would be quite efficient for that.

(WAL archiving is not too good for this purpose because of high lag. I just need to minimize the cross-datacenter traffic keeping the replication lag low.)
