You could drop and re-create the replication slot, I guess. But your nodes would be hopelessly out of sync and need manual resync (with data replication disabled) of one node vs another.
Thanks for pointing to replication slot.
I Simulate the similar situation in dev env by remove the wal segment on node1, when node2 keep inserting into a table, now it perfectly can move forward to latest wal segment, but the difference situation is at node_status.
In production node_status is i in node1 but r in node2, where on my dev both nodes keep r , even I waited to let it may change quite long.
can I safely update the node_status directy on bdr.bdr_nodes?
