Well, it seems to work only with "timestamp without time zone" type. But
worked. Thanks a lot.
For me it's a new approching not using functions such as time, but
"casting" it to a "time" type ( like <sql>select materiadata::time from
materia;</sql>).
If PostgreSQL development group change it's point of view, I suppose
there's some advantage. Do you know some advantages ??
