Yup. It was never intended that 'null' would be valid input for
to_timestamp, and that's thrown an error since 8.4. See thread here:
http://www.postgresql.org/message-id/37ed240d0808291839t21e19956mdfbdc80aeb1b3c19@mail.gmail.com
A quick test says that 8.3 and older did this:
regression=# select to_timestamp('null','yyyy-MM-dd hh24:mi:ss');
to_timestamp
---------------------------
0001-01-01 00:00:00-05 BC
(1 row)
which can hardly be considered a sane interpretation of 'null', even
if we wanted to accept that input.
