[...]Sorry to bother again about that, but what about the "detached node cleanup" best practice? Suppose I have 2 nodes, 'node1' and 'node2'. So I am OK to call bdr_part_by_node_names('node2') on node1 to detach node2. But then, is it safe to call bdr_part_by_node_names('node1') to do the cleanup on node2, or should I better call pg_drop_replication_slot('...') instead?BDR 0.9.1 drops the slot on remaining nodes correctly on node part, so no further action is required there. Just part_by_node_names the node you are removing, running the query from one of the nodes you wish to retain. (0.9.1 enforces this). If you want to retain the node you're removing as a standalone, it should be sufficient to drop any slots on that node, truncate bdr.bdr_nodes and bdr.bdr_connections, and remove the bdr security label with: SECURITY LABEL FOR bdr ON DATABASE thedb IS NULL; then restart the DB. You may also wish to remove 'bdr' from 'shared_preload_libraries'.
