Build-farm - intermittent error in 031_column_list.pl

Hi hackers.

FYI, I saw that there was a recent Build-farm error on the "grison" machine [1]
[1] https://buildfarm.postgresql.org/cgi-bin/show_history.pl?nm=grison&br=HEAD

The error happened during "subscriptionCheck" phase in the TAP test
t/031_column_list.pl
This test file was added by this [2] commit.
[2] https://github.com/postgres/postgres/commit/923def9a533a7d986acfb524139d8b9e5466d0a5

~~

I checked the history of fails for that TAP test t/031_column_list.pl
and found that this same error seems to have been happening
intermittently for at least the last 50 days.

Details of similar previous errors from the BF are listed below.
