I played with this some more. Here is the exact error message:
ERROR: manifest requires WAL from final timeline 1 ending at 0/1967C260, but this backup starts at 0/1967C190
By trial and error I found that when I run a CHECKPOINT on the primary,
taking an incremental backup on the standby works.
I couldn't fathom the cause of that, but I think that that should either
be addressed or documented before v17 comes out.
