Thanks for the report. It would be possible to switch to a second
approach here, where we use pg_free() if we don't have a
locale->db_locale to make sure that the memory is freed in its correct
context, like in the attached. What do you think?
This test has been added in v16 via 9637badd9f92, with the buildfarm
not complaining. Could it be possible to improve the situation so as
we would know about 002_pg_upgrade.pl failing for such cross-upgrades
like what you are doing here?
