Sorry Laurenz,

My reply did not get threaded appropriately.
My original question was here:
https://www.postgresql.org/message-id/a74d5732-60fd-d18b-05fd-7b2b97099f19%40imap.cc
I'd like to prioritize walsender for replication not to lag too much.
Otherwise, when I have load spikes on master, standby lags, sometimes by 
hundreds of gigabytes.

Best, Alex
