This method will register a new function which will be useable in an SQL
query as a COLLATE option for sorting. The method's parameters are:
=over

The name of the function. This is the name of the function as it will
be used from SQL.

By default, the collations "perl" and "perllocale" are created for you.
These allow sorting in Perl terms using "cmp", in both locale and non-locale
forms. For example, the following does a locale-aware Perl cmp sort.
SELECT * FROM foo ORDER BY name COLLATE perllocale
