Actually this is sort of expected. Your locale configuration expects a
certain encoding; all databases should be created using that encoding
for string comparison to work properly. What definitely is a bug is the
fact that CREATE DATABASE allows you to create a database with an
encoding different from the one defined by initdb.

The conclusion is that you should create your databases using UTF-8
encoding if you are using cs_CZ.UTF-8, otherwise it won't work as
expected.
