Please reply to the list also in the future, I'm going to sleep now.
Anyway, it still works:

kleptog=# create temp table x (a text);
CREATE TABLE
kleptog=# insert into x values (nullif('',''));
INSERT 114760 1
kleptog=# insert into x values (nullif('1',''));
INSERT 114761 1
kleptog=# select a,a is null as isnull from x;
 a | isnull
---+--------
   | t
 1 | f
(2 rows)

Please show us the error you got.

Have a nice day,
