That's automatically taken care of by the executor. Functions need to
handle NULL inputs if they are *not* strict.

#select proisstrict from pg_proc where proname = 'interval_avg_serialize';
 proisstrict

(1 row)

#select proisstrict from pg_proc where proname = 'interval_avg_deserialize';
 proisstrict
-------------
 t
(1 row)
