assuming you want to add expdays days to the CURRENT_DATE, you can just use + arithmetic of date:
# SELECT CURRENT_DATE + 5 as in_the_future_after_5_days;
in_the_future_after_5_days

Check this out:
# select current_timestamp, current_timestamp + interval '2' day;
now | ?column?
-------------------------------+-------------------------------
2013-12-16 01:16:19.783235+01 | 2013-12-18 01:16:19.783235+01
(1 row)
AFAIK that should also be SQL compliant.
