Re: encoding of PostgreSQL messages

Hi.

Sorry very late reaction.
I desire problem solution.Therefore, one evidence....

I tried jdbc program.
http://winpg.jp/~saito/pg_work/LC_MESSAGE_CHECK/connect_problem/jdbctestx.java
C:\home\HIROSHI>java jdbctestx
org.postgresql.util.PSQLException: FATAL: ???[??"postgres"??????????????
at org.postgresql.core.v3.ConnectionFactoryImpl.readStartupMessages(Conn
ectionFactoryImpl.java:444)
at org.postgresql.core.v3.ConnectionFactoryImpl.openConnectionImpl(Conne
ctionFactoryImpl.java:99)
at org.postgresql.core.ConnectionFactory.openConnection(ConnectionFactor
y.java:66)
at org.postgresql.jdbc2.AbstractJdbc2Connection.<init>(AbstractJdbc2Conn
ection.java:124)
at org.postgresql.jdbc2.Jdbc2Connection.<init>(Jdbc2Connection.java:24)
at org.postgresql.Driver.makeConnection(Driver.java:386)
at org.postgresql.Driver.connect(Driver.java:260)
at java.sql.DriverManager.getConnection(Unknown Source)
at java.sql.DriverManager.getConnection(Unknown Source)
at jdbctestx.main(jdbctestx.java:21)

Then, server log is this.
