BUG with decimal type

Hi,

sorry if this is already fixed, but under Postgres 6.5.1. (debian 6.5.1-6)
the following ..

create table VAT (  objectid     integer not null primary key,  ts           integer not null,  vatlevel
decimal(18,2)not null,  orderby      integer not null
 
);
create unique index VAT_level_idx on VAT ( vatlevel );

.. yields:

"ERROR:  Can't find a default operator class for type 1700."

Regards,
