Description of problem:
psql does not allow to communicate with UNICODE databases when use 'advanced' columns descriptions.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. Install and run postgres server
2. Create db with UNICODE encoding 
     $ createdb -E UNICODE mydb
2. Set KOI8 locale 
     $ export LANG=ru_RU.koi8r
3. Connect to this DB from terminal with KOI8 encoding
     $ psql -d mydb
5. Set RIGHT encoding to communicate with DB
     mydb=> \encoding KOI8
6. Just create table with 'PRIMARY KEY' specifier (I've got this table description from pgsql docs at http://www.postgresql.org/docs/7.3/interactive/ddl-constraints.html#AEN1849
)
     mydb=> CREATE TABLE products (
     mydb(>     product_no integer PRIMARY KEY,
     mydb(>     name text,
     mydb(>     price numeric
     mydb(> );
     ERROR:  ignoring unconvertible UTF-8 character 0xd3cf
     mydb=>

Actual Results:       ERROR:  ignoring unconvertible UTF-8 character 0xd3cf
and nothing happen

Expected Results:  created table

Additional info:

If I remove PRIMARY KEY keyword, everything is OK.

Moreover, with UNICODE it's not really useful too:
1. Turn terminal to have UTF-8 encoding
2. Set corresponding encoding at command prompt
   $ export LANG=ru_RU.utf8
3. Connect to same unicoded DB
   $ psql -d mydb
4. Set right encoding (I don't really need it, but) 
   mydb=> \encoding UNICODE
5. Try to create table with primary key column
   mydb=> CREATE TABLE products ( product_no integer PRIMARY KEY, name text, price numeric);
NOTICE:  CREATE TABLE / PRIMARY KEY \uffff\uffff\uffff\uffff\uffff\uffff\uffff \uffff\uffff\uffff\uffff\uffff\uffff\uffff\uffff\uffff\uffff\uffff\uffff\uffff\uffff\uffff \uffff\uffff\uffff\uffff\uffff\uffff "products_pkey" \uffff\uffff\uffff \uffff\uffff\uffff\uffff\uffff\uffff\uffff "products"
CREATE TABLE
    
At my gnome-terminal this '\uffff' showed as a small squares. 
As far as I understand, there should be russian-language messages about creating additional index "products_pkey" on table "products".

but when I put \d command, everything is OK and showed in russian with right encoding
