I believe there's more than that... Probably the "+1" should be outside the
date_trunc, anyway. It might help, but I still see the need to to do
calculations... Specially if it was Tuesday today...

neo=# select date_trunc('dow', current_date + 1);
ERRO: unidades de timestamp with time zone "dow" são desconhecidas
neo=# select date_part('dow', current_date + 1);

neo=# select date_trunc('week', current_date + 1);
