Hmm, ich kann den Fehler auf meiner Postgres-DB (7.2.1_1/FreeBSD) nicht reproduzieren. 
Folgendes Skript läuft problemlos:

  require "dbi"

  DBI.connect("dbi:Pg:mneumann", "user", "passwd") do |dbh|
    dbh.do "CREATE TABLE artikel ( artikelnr VARCHAR(30) )"
 
    dbh.do "INSERT INTO artikel VALUES ('test')"
    dbh.do "INSERT INTO artikel VALUES ('test2')"
    dbh.do "INSERT INTO artikel VALUES ('ö')"

    p dbh.select_one("SELECT * FROM artikel WHERE artikelnr = 'ö'") # => ['\366']

    dbh.do("DROP TABLE artikel")
  end
 

Probier mal in "psql" die Query, die bei dir nicht funktioniert, abzusetzen.
