Well, I tried:

select current_date, CURRENT_DATE - INTERVAL '1 DAY';

but receive the following:

ERROR: There is no operator '-' for types 'date' and 'timespan'
You will either have to retype this query using an explicit cast,
or you will have to define the operator using CREATE OPERATOR

After trying somethings, I was able to get this to work:

select CURRENT_DATE -1;

will subtract 1 day from the current date... which gives me what I need
for now.

Thanks
