version: PostgreSQL 11.4
OS: Windows 10
This is an illustration of my question:
On 3 different machines there are one primary server per machine.
Is it possible to have one common server where replicas of these primary servers are?
When configuring a replica, I am instructed to delete the current database (the
PGDATA directory), if there is one. Thus my question. If I already have a replica on that database, it is then deleted?
Do I have to have several installations of PG? Having them on their own VM's?
