Hmm. Well, if we use pg_tolower then it will only do the right thing
for ASCII letters, but it seems like non-ASCII in the path leading to
the postgres binaries would be pretty dang unusual. (And I am not
convinced tolower() would get it right either --- it certainly won't
if the encoding is multibyte.)
On balance I'd suggest just using pg_tolower and figuring it's close
enough.
