Why is it not expected behavior?  The SQL99 spec has not changed from
what it said when we discussed this last year: case conversion of
identifiers is *not* to be done in plain-ASCII rules.  Admittedly it
says "unicode" and not "locale", but you'd have the same problem if we
had a full unicode implementation, no?

My feeling is that the best answer is to use lower case names to
reference identifiers in the initdb code.  This is not a real pleasant
prospect, but I can't see giving up on spec-compatible case folding ...
