Hello,

I could not get to this info via JDBC directly, but sniffing on port 5432
reveals the following output when the SHOW commands are run:

NOTICE:  Current server encoding is 'UNICODE'.
NOTICE:  Current client encoding is 'UNICODE'.

It seems correct to me, so the question about Unicode's slowness remains.
I guess that I will have a look at the driver's internals. Do you believe
that the backend should not be much slower [than LATIN1] when delivering
query results in the UNICODE encoding?
