Re: BDR 1.0: background worker wants to start that should not bethere

Hi.

You have deleted the node from BDR setup, but you still have to delete it from the postgres logical replication:

SELECT * FROM pg_replication_slots;
SELECT pg_drop_replication_slot('YOURSLOT');

As a remark, based on my BDR experience, when your cluster has been damaged, your best option is to rebuild it.

Hi all,



After I used bdr.bdr_part_by_node_names(*p_nodes text[]*) and removed the
nodes from bdr.bdr_nodes table I still get log errors about the nonexistent
pg_replication_slot:



< 2019-02-12 06:26:21.166 PST >LOG:  starting background worker process
"bdr (6208877715678412212,1,22576474,)->bdr (6449651545875285115"



How does postgresql deduce which workers need starting?

Is there a table I am missing?
