Using a glibc system, initdb with --locale=tr_TR (or tr_TR.utf8 or 
whatever) and run make installcheck.  You should see test failures in 
the tsearch and tsdicts tests that appear to relate to issues with 
lowercasing the "I" letter correctly.  And then use your language skills 
to determine what the correct behavior is. ;-)

Note that on Mac OS X with tr_TR locales, the tests do not fail.

I actually suspect that both current answers are wrong.
