If they actually are using locale C, I would say this is a bug.
That should designate memcmp sorting and nothing else.
Sounds like a bug to me. This is happening with a PostgreSQL cluster
created and served by a build of commit c04c6c5d6f :
=# select version();
PostgreSQL 16devel on x86_64-pc-linux-gnu, compiled by gcc (Ubuntu
11.3.0-1ubuntu1~22.04) 11.3.0, 64-bit
=# show lc_collate;
C
=# select '+' < '-';
f
If the database is created with locale provider ICU, then lc_collate
does not apply here, so the result might be correct (depending on what
locale you have set).
=# select '+' < '-' collate "C";
