Hi,


  *
Is that multi master replication is not recommended to do ?
  *
If we can do, can I get any resource for implementing that on PostgreSQL which is open-source?



Thanks,
Vidyshree H S

Thanks all for your inputs.


  *
Currently I'm working on active-passive(Primary and standby scenario).
  *
I'm preparing one study report on active-active node implementation which talks about active-active nodes background, theoretical explanation, implementation part which includes some trails on this. For that, I'm checking for the resources.



Thanks
Vidyashree H S

Agreed, see this:
