then what is the point of multi master :) 

if the server goes down, both go down.

other than that, having multiple servers may act as noisy neighbors to each other.

Hi,

I'm asking this out of curiosity, if I have 2 postgres nodes on same server,

1. listening on port 5432

2. listening on port 5433

What issue's I might face if I do it like this? Assuming I'm doing this for multimaster approach.

pg_ctl -D /data/postgres -o "-p 5432" -l /var/log/pg1 start

pg_ctl -D /data/postgres -o "-p 5433" -l /var/log/pg2 start

Happy to help :)
