According to
https://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=rhinoceros&dt=2018-02-08%2001%3A45%3A01
there's still an intermittent issue. I ran "make installcheck" in
contrib/postgres_fdw in a loop, and got a similar failure on the
47th try --- my result duplicates the second plan change shown by
rhinoceros, but not the first one. I speculate that the plan change
is a result of autovacuum kicking in partway through the run.
