When I went to update the docs, I found they already said 5.8.3
is the minimum. Excavating in the git log led me to this old
discussion:
https://www.postgresql.org/message-id/flat/16894.1501392088%40sss.pgh.pa.us#2c7641fa2459e84049301f185d74d429
So it was intentional at the time to leave configure's check
as 5.8.0. However, given that the functionality available is
less than you'd expect, and that we've not tested any such
configuration in several years, I still concur with adjusting
configure to require 5.8.3. Pushed it that way just now.
