.partial files are at the end of a timeline, so they will be ignored
now (and this even if a node on the old timeline archives the same
segment as the .partial one sent by the promoted standby). And as
pg_xlogdump is not able to follow a timeline jump there is nothing we
would need to do:
$ pg_xlogdump 000000010000000000000006 000000020000000000000008
pg_xlogdump: FATAL: could not find file "000000020000000000000006":
No such file or directory
$ pg_xlogdump -t 1 000000010000000000000006 000000020000000000000008
pg_xlogdump: FATAL: could not find file "000000020000000000000006":
No such file or directory
I am not convinced that it is worth to make pg_xlogdump follow
timeline jumps as well.. One could just run it twice on the old and
new timeline segments to get the output he wants.
