Aha.. I'm in Eastern (Canada), and doing this for any switch from EST to
EDT causes the problem.. e.g. April 1st of this year:

=> select timestamp(date('2001-04-01'));
timestamp
------------------------
2001-03-31 23:00:00-05
(1 row)

This skewed timestamp then gives the wrong day for the date_part. I think
that time switches in EST/EDT are supposed to happen at 2am, not midnight,
to help avoid this kind of thing.
