Commit 3ca43dbbb67f which adds the permission checks seems to cause conflicts
in the pg_upgrade tests:
https://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=piculet&dt=2024-05-13%2008%3A36%3A37
There is an issue with dropping and creating roles which seems to stem from
this commit:
CREATE ROLE regress_partition_merge_alice;
+ERROR: role "regress_partition_merge_alice" already exists
