Will this go into the same database?
If so, you should probably use:

CREATE TABLE targettable AS
select data,
usuario,
sum(pontos) as sum_pontos,
sum(wus) as sum_wus
from usuarios
group by data, usuario;

If you are going to insert this into another database,
consider doing the step above and then use

pg_dump -t targettable to get a nice dump you can easily
restore. You can also use copy to dump your own.
