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
  =# select '+' < '-' collate "C";
  t

I don't know if it should matter but also:

  =# show lc_messages;
  C

--strk;
