Description:        steps to reproduce BUG #1438: Non UTF-8 client encoding
problem
Details:

That was really easy to reproduce:
$ export LANG=ru_RU.koi8r
$ createdb -E UNICODE mydb
$ psql -d mydb
mydb=# \encoding KOI8
mydb=# create table a (aa integer);
CREATE TABLE
mydb=# create table b (bb integer primary key);
ERROR:  ignoring unconvertible UTF-8 character 0xd3cf
mydb=# \d

mydb=#

So, it's always a problem when I put PRIMARY KEY modifier after column
declaration with KOI8 encoding.
