Btw,...

There are only 15 cases in the utf8 repertoire that depends on locale, these are the only cases where pg should report:

ERROR: invalid multibyte character for locale
HINT: The server's LC_CTYPE locale is probably incompatible with the database encoding.

When doing a select upper/lower (col)
All others should work just fine.

The error should probably also be changed to a warning, and just return the offending character unmodified.
