Regression test failure in regression test temp.sql

Hi all,

While browsing the buildfarm failures, I have found this problem on
anole for the test temp:
https://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=anole&dt=2019-08-07%2006%3A39%3A35
select relname from pg_class where relname like 'temp_parted_oncommit_test%';
relname
----------------------------
- temp_parted_oncommit_test
temp_parted_oncommit_test1
(2 rows)

drop table temp_parted_oncommit_test;
--- 276,283 ----
select relname from pg_class where relname like 'temp_parted_oncommit_test%';
relname
----------------------------
temp_parted_oncommit_test1
+ temp_parted_oncommit_test
(2 rows)

This could be solved just with an ORDER BY as per the attached. Any
objections?

Thanks,
