Bruce,
This is extremely bad news, because if will make PostgreSQL 6.5 unusable for
most of my applications. Perhaps something can be done to resolve this
situation?
I understand the problem for 16-bit characters support, but for most of the
encodings that support only 8 bit characters it should be safe to assume the
maximum character value is 255.
Anyway, making this check compile-time defined would certainly fix things
here, because in my case the cyrillic letters order match that of the binary
encoding (that is, the first alphabet letter is before the second etc).
Perhaps the locale data can be used to gather this information?
I will do some testing without using locale to see what happens.
Regards,
Daniel
