[EUC_CN] Failed to connect through user created user/database using simplified Chinese characters

Hi,
It was observed that when we try to connect through a user/database created
using
simplified Chinese characters on EUC_CN server_encoding, it fails giving
error that
the object does not exists. Whereas if we query the system table we can
find their entries
there.

Data setup:
.) set the locale to zh_CN.UTF8
[neha(at)localhost bin]$ locale
LANG=zh_CN.UTF-8
LC_CTYPE="zh_CN.UTF-8"
LC_NUMERIC=zh_CN.UTF-8
LC_TIME=zh_CN.UTF-8
LC_COLLATE="zh_CN.UTF-8"
LC_MONETARY=zh_CN.UTF-8
LC_MESSAGES="zh_CN.UTF-8"
LC_PAPER=zh_CN.UTF-8
LC_NAME="zh_CN.UTF-8"
LC_ADDRESS="zh_CN.UTF-8"
LC_TELEPHONE="zh_CN.UTF-8"
LC_MEASUREMENT=zh_CN.UTF-8
LC_IDENTIFICATION="zh_CN.UTF-8"
LC_ALL=

.) Perform initdb
[neha(at)localhost bin]$ ./initdb -D /tmp/data --locale=zh_CN

Just wondering, is there anything wrong I am doing or it's a bug?

Thanks.
