Is this a 7-bit ascii database name? (it looks like it is, but I thought
I'd check).

There isn't much the JDBC driver can do here -- the encoding of messages
early on during startup protocol isn't specified AFAIK, so the driver
just assumes 7-bit ascii in the current development driver or (from
memory) the default JVM encoding in older drivers.

What version is the server?

What's the encoding in use on the database side? What about the default
JVM encoding on the client side?

Do you see the same problem if you try the current development driver
from jdbc.postgresql.org?

Is there any chance of getting a tcpdump or similar of the connection
attempt?
