That expression returning an interval would be contradictory
to the documentation and a simple test:
| tim=# SELECT CURRENT_DATE - '2009-12-31';
| ?column?
| ----------
| 138
| (1 Zeile)
| tim=# SELECT CURRENT_DATE::TIMESTAMP - '2009-12-31';
| ?column?
| ----------
| 138 days
| (1 Zeile)
| tim=#
So how far away from "this kind of select" is your actual
query?
