Weird, it works fine for me:

$ PGCLIENTENCODING=SJIS psql regression
Welcome to psql 7.4devel, the PostgreSQL interactive terminal.

Type:  \copyright for distribution terms      \h for help with SQL commands      \? for help on internal slash commands
    \g or terminate with semicolon to execute query      \q to quit
 

regression=# \encoding
SJIS
regression=# show client_encoding;client_encoding
-----------------SJIS
(1 row)

regression=# select pg_client_encoding();pg_client_encoding
--------------------SJIS
(1 row)

I would not have been real surprised to hear that psql's \encoding is
out of sync, but it *does* surprise me that "show client_encoding" might
not match pg_client_encoding().  I would think those are looking at the
same backend state variable.  Any theory how that could happen?
