Hi Sajan,
What is meaning of Active/Active setup for you? Postgres provides 1 master (read/write) server and multiple synchronous/asynchronous (read-only) slave server with streaming replication build-in. If you want multiple master (read/write) PostgreSQL server, you should use an additional tool like BDR (Bi-Directional Replication), EDB Replication Server etc. Also Postgres-XC may be taken your interest.
Best regards.

Thanks Samed. That sure works.I have followed the documentation that you have provided at https://www.digitalocean.com/community/tutorials/how-to-set-up-master-slave-replication-on-postgresql-on-an-ubuntu-12-04-vps and the replication works perfectly fine. I am assuming this works perfectly fine for an Active/Passive setup, however I am wondering on how to setup Active/Active kind of an replication setup.Is Active/Active possible with postgres database, if so is there any documentation that I can follow to setup Active/Active replication ?Thank You.Thank You,Sajan GoneFrom: Samed YILDIRIM <samed@xxxxxxxxxx>

I was able to successfully set the replication up (Master/Slave, Hot stand by).I really appreciate your help on this.My background is mostly on MySQL so my next question would be on how to look at the replication status. Like MySQL “Show slave status \G” command is there any command on postgres to look at the slave current status(or replication status).Thank You,Sajan Gone.From: Samed YILDIRIM <samed@xxxxxxxxxx>

Hello,Good afternoon everyone.
This is Sajan Gone, I am trying to setup a Standard Master/Salve replication between two postgres instances. I am pretty much new to postgres and not exactly sure how replication works and what is an architecture behind
it. As of now I am following the standard postgres documentation @ https://www.postgresql.org/docs/current/static/warm-standby.html#PREPARING-MASTER-FOR-STANDBY,
however it is slightly difficult for me to understand.
It would be very helpful if any one could guide me in a proper way on setting up Master/Slave replication on postgres. Any recommendations on good documentation
or study materials on postgres replication would be highly appreciated.
Many Thanks in advance.
Thank You,Sajan Gone
