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
