If you redirect you syslog to another server, the "pg_log" will be written in
/var/log/... and pg_log will just write that it has been redirected.

BDR works fine for writeloads that are geographically separate.  True multi-master is ACID compliant when you have a global transaction manager like Postgres-xc or Postgres-xl.

I am using Bucardo.
It is working fine. It has been runinning for 5 years across 50 replicated nodes.
I strongly recommend Bucardo for master-master replication.
It is trigger based asynchronous replication system.

Please note that I'm open for any other replication method that would allow
better scalability. One of the best option would be to have Multi-master
setup though I haven't seen any documentation around the support for such
capability by Postgres.


Postgresql doesn't support multi-master in the core project but there are options available. Have you come across BiDirectional Replication (BDR) yet? https://2ndquadrant.com/en/resources/bdr/
