使用環境：Windows server 2008 ENT R2
PostgreSQL: 9.1

連接資料庫時，會出現：

C:\Users\Administrator>psql -d book -U sa
psql (9.1.1)
WARNING: Console code page (437) differs from Windows code page (950)
         8-bit characters might not work correctly. See psql reference
         page "Notes for Windows users" for details.
Type "help" for help.
book=# select * from bookdata;

如果我做以下的動作：

C:\Users\Administrator>chcp 950
使用中的字碼頁: 950
C:\Users\Administrator>psql -d book -U sa
psql (9.1.1)
頛詨 "help" 憿舐內隤芣???

book=#

中文出現了，但在連接及SELECT 的部分結果還是亂碼，請各位高手幫忙如何讓整個顯事都正常，謝謝！
p.s.我設過\encoding為UTF8也沒用。。。
