Hi Joao,

T hanks for testing it, and for checking the order of operations.

The patch came out of that thread. That message is where David said
-f should not override the check. v3 keeps it and adds this thread as
a second Discussion line.

Yes. The server reads tablespace_map only when backup_label is there.
Without backup_label it renames the file to tablespace_map.old and
starts as usual. So tablespace_map alone does not stop the server from
starting, and there is nothing for pg_resetwal to guard against.
v3 also leaves out the --cluster-state patches, as David suggested.
0001 and 0002 have no code changes.

Thanks,
Shihao
