Wow, what a deep story for just a couple of lines!

+1 for trying to revert in master.

I think there's more benefit than possible harm. There are ~4 similar
failures a month on master. If we resurrect walreceiver problems, we will
notice soon. There were like ~20 failures a month. And a8458f508a7 commit
message looks promising (I do not understand commit itself).

Best regards, Andrey Borodin.
