I have equipped this part with a proper error message now.  At the time 
I was thinking this is a "can't happen" error, but it has in fact 
already helped clarifying some other regression test run failures for me:

./pg_regress --inputdir=. --dlpath=. --multibyte=SQL_ASCII 
--load-language=plpgsql  --temp-install=./tmp_check 
--top-builddir=../../.. --temp-port=565432 --schedule=./parallel_schedule
