In the meantime lower() can come to the rescue. It's not nearly as easy to fix as the reporter of that bug imagines, because we don't know the relationship between pg_wchar representation and the wchar_t representation assumed by the <wctype.h> functions. In the short term it should work if you can use a single-byte encoding (koi8r I suppose) and a locale setting compatible with that. regards, tom lane
