Well, I don't have a problem reading long texts; my problem is that I'm
unable to argue as quickly.

I do buy your argument, though (if reluctantly); in particular I was
worried to offer a parameter (to turn off zero-filling of segments) that
would enable dangerous behavior, but then I realized we also have
fsync=off of which the same thing can be said.  So I agree we should
have two GUCs, properly explained, with a warning where appropriate.
