It seems a CPU-native client program that uses JDBC driver via
JNI and some kind of protocol error happened. (I recomment to use
libpq directly..)

At first, please provide the version of the JDBC driver and a
full stack exception, not only the last one, then ask the
following mailling list.

If you can parepre a small self-contained stuff to replay your
problem, it would be a great help for others. I suppose it is
feasible as a small Java program not using JNI.

It takes (modified) UTF8 string. As far as I can see '0x80' (�
in CP1252) doesn't work for the function..

If you NewByteArray'ed the pcCharArray and using "CP1252" in the
former case, it would work on a German environment and you will
get 'ungültige Zeichenkette in Message' instead if something's
wrong in sending a query. It seems that the error happend at bind
time. Anyway full stack exception gives a crue to that.
