Nevertheless, in PostgreSQL there is the following default order for their sorting: "By default, null values sort as if larger than any non-null value; that is, NULLS FIRST is the default for DESC order, and NULLS LAST otherwise." (https://www.postgresql.org/docs/current/queries-order.html). Nulls ordering can be changed by. The NULLS FIRST and NULLS LAST options can be used to determine whether nulls appear before or after non-null values in the sort ordering. Do you see this or something contrary to?
