You're not so stuck with what the plateform provides as you can define your own collation with glibc. Here a quick exemple with an ebcdic collation based on glibc: https://www.postgresql.org/message-id/flat/20230824162653.34eb3bad%40karst#31c548587bc98686e010e500a2f97d97 It's probably another level of maintenance to provide a stable UTF8 collation using such a procedure though. But it seems possible at least.
