I don't think you can:
postgres=# select INTERVAL '1 week' + 'infinity'::timestamp;
?column?
----------
infinity
(1 row)
postgres=# select INTERVAL 'infinity' + now();
ERROR: invalid input syntax for type interval: "infinity"
Also notice the limits that the Interval datatype supports.

You might need to rethink your design to two timestamps, or use a null
represent to concept of infinite duration since postgresql doesn't
currently support this.
