Active-Passive DB
Hi PG,
In PG , can we have Active1 , Passive1 , Passive2 cluster.
Now all active1 data is present in passive1 and 2.
but when any delete query runs on active1 , same should get replicated on
passive1 But delete should not get triggered on passive2.
so passive2 can be used as archival db.
if active1 fails then , passive1 will become active2.
Thanks

You would need logical replication for passive2.
Yours,
