To be clear, what sulfinu is really advocating is convergence on
Unicode period, which is the direction most international projects are
moving, when they can. PostgreSQL's problem is that it (and AFAICT
POSIX) conflates encoding with locale, when the two are entirely
separate concepts.
I'm not entirely sure how that's supposed to solve the client
authentication issue though. Demanding that clients present auth data
in UTF-8 is no different than demanding they present it in the
encoding it was entered in originally...
