Collation is a function of the OS. Basically, is the locale of your
database setup for UTF-8 collation? It would probably be called
hr_HR.UTF-8.

Yes, setup the locale correctly. In general, postgresql should give the
same results as sort(1) on the command-line. Use that to experiment.

LC_ALL=hr_HR.UTF-8 sort < input > output

Hope this helps,
