You are correct, Andreas.
=> select now()>'Jul 14 2006 9:16:47AM';

t
(1 row)
=> select now() > CASE WHEN 'Jul 14 2006 9:16:47AM' IS NOT NULL THEN
'Jul 14 2006 9:16:47AM' END;
?column?

I've also found that there must be more than one typecasting function
being used because the result can be different depending on the format
of the timestamp string:
=> select now()>coalesce('Jul 14 2006 9:16:47AM');
?column?
----------
f
(1 row)
=> select now()>coalesce('2006-07-14 9:16:47');
?column?
----------
t
(1 row)
