Subject: pgsql: Ensure all pg_locale.h APIs work with collate_is_c.
Date: Thu, 20 Aug 2026 16:41:25 +0000
Message-ID: <E1wx5pU-00000001Ns3-2TpO@gemulon.postgresql.org> (raw)
Ensure all pg_locale.h APIs work with collate_is_c.
Safer for callers, so that checking collate_is_c is only needed if the
caller wants to optimize for that case.
Backpatch to avoid creating a hazard for other backpatches in this
area.
