Assuming that the locales on FreeBSD are the same or closely related to 
the ones on Mac OS X, I would rather say that the BSD locales are 
broken, because they don't actually support the Turkish case conversion 
rules:

regression=# show lc_ctype;  lc_ctype
------------- tr_TR.utf-8
(1 row)

regression=# select lower('SKIES'); lower
------- skies
(1 row)

regression=# select upper('skies'); upper
------- SKIES
(1 row)


Thus, the problem that the glibc locales appear to expose is masked here.
