It seems like this commit has resulted in some buildfarm instability:

https://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=lousyjack&dt=2020-03-28%2006%3A33%3A02

apparent change of plan

https://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=petalura&dt=2020-03-28%2009%3A20%3A05
https://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=petalura&dt=2020-03-28%2013%3A20%3A05

unstable results in stats_ext test

I initially thought that Dean's functional-stats adjustment might be
the culprit, but the timestamps on these failures disprove that.
