8.0.0beta4: "copy" and "client_encoding"

Hi,

The following statement worked fine with 7.4 but fails under 8.0.0beta4:

SET CLIENT_ENCODING TO 'LATIN1';

Error message:

08006
The servers client_encoding parameter was changed to {0}.
The JDBC driver requires client_encoding to be UNICODE for
correct operation.

Is this a bug or a new restriction of the JDBC driver/server backend?

That's the (faulty) 8.0.0beta4 configuration:

Default client encoding: LATIN1
Database encoding: UNICODE
DBMS: 8.0.0beta4
JDBC driver: pgdev.307.jdbc3.jar
File encoding: LATIN1

That's the 7.4.x configuration:

Default client encoding: LATIN1
Database encoding: UNICODE
DBMS: 7.4.x
JDBC driver: pg74.213.jdbc4.jar
File encoding: LATIN1
