I committed that suggestion, but I'm not sure it's enough to fix it,
because if I do

LANG=cs_CZ.utf8 make check

then I still get variant output order. I tried about six different
spellings of the query without improving matters, so I'm totally
baffled. Have we managed to break COLLATE "C"? (With one eye on
Jeff Davis' recent stuff, I could believe that, except I'd have
expected it to show up in other regression tests already.)

I'll await buildfarm results, but there's something odd here.
