To retrieve the number of references to a particular support.

CREATE FUNCTION number_of_support_references(integer) returns bigint
AS 'select count(photo_tech.identifier)
      from photo_tech, support
     where photo_tech.support=support.identifier
       and support.identifier = $1' LANGUAGE 'sql';
