Rather than offering a patch, you need to convince us why our reading of
the SQL standard is wrong.  ("Oracle does it that way" is not an
argument that will carry a lot of weight.)

SQL99 states that identifier case conversions are done on the basis of
the Unicode upper/lower case equivalences, so it seems clear that they
intend more than ASCII-only conversion for identifiers.  Locale-based
conversion might not be an exact implementation of the spec, but it's
surely closer than ASCII-only.
