lexicographical ordering in postgres - Mailing list pgsql-general

Hi!
I created a table in postgres with varchar values in it, and I noticed that
postgres lexicographical ordering is weird in the sense that it ignores
whitespaces.
please look at the result I got:

select * from tablename order by columnname;
            cloumnname
      -------------------------------------
            one 1
            one  1
            one 12
            one 2
            one 30
      (5 rows)
      This means that 'one<space>1' and 'one<space><space>1' are the same
lexicographically.
Is this correct?
thanks
