<para>
The ordinal number refers to the ordinal (left-to-right) position
of the result column. This feature makes it possible to define an ordering
- on the basis of a column that does not have a proper name.
+ on the basis of a column that does not have a unique name.
This is never absolutely necessary because it is always possible
to assign a name to a result column using the AS clause, e.g.:
<programlisting>
descending sort order nulls sort at the beginning.
</para>
+ <para>
+ Data of character types is sorted according to the locale-specific
+ collation order that was established when the database cluster
+ was initialized.
