It looks like the actual problem is that, when pg_regress creates the
database in --no-locale mode, it passes LC_COLLATE='C' and
LC_CTYPE='C', instead of just LOCALE='C'.
Before my commit, the two were equivalent so it didn't matter, but
afterwards it created an inconsistency that left daticulocale as cs-CZ.
Patch attached.
