No, I do not think it's the fault of the buildfarm machines. The problem
is that Magnus got rid of a bad commit into the 9.2 branch via "git reset"
not "git revert", cf
https://www.postgresql.org/message-id/CABUevEzrD-BYtQOQ22navkoWquOC5TcqPcBS_iQ2cYqaK9_39g%40mail.gmail.com
and these three machines seem to have been quick enough to see the
intermediate state and get confused by it. I'm not very sure why "git
pull" isn't enough to recover, but it evidently isn't.
