This works fine for me on Fedora 37:

$ cd src/bin/psql
$ LANG=cs_CZ.utf8 make installcheck
make -C ../../../src/backend generated-headers
make[1]: Vstupuje se do adresáře „/home/tgl/pgsql/src/backend“
...
# +++ tap install-check in src/bin/psql +++
t/001_basic.pl ........... ok
t/010_tab_completion.pl .. ok
t/020_cancel.pl .......... ok
All tests successful.
Files=3, Tests=169,  6 wallclock secs ( 0.06 usr  0.02 sys +  2.64 cusr  0.99 csys =  3.71 CPU)
Result: PASS

I wonder if you have something inconsistent in your locale
configuration.  What do you see from

$ env | grep '^L[CA]'
