Hello,I have a 2 node BDR group and replication is happening properly. if i bring down one of the node's interface, after sometime the replication slots are becoming inactive (pg_replication_slots view). Then if i bring back interface slots are not turning active automatically and replication stops. Any idea why automatically its not re-established ?
May be postgres does not detect the link is down.
You could try modifying the connection strings, so that postgres detects earlier the problem, like described in this post :
