This is (still) a problem with Postgres optimizing untyped constants
by evaluating them at table creation time rather than at run time.
Redefine your datetime field as

  ...
  added datetime not null default text 'now',
  ...

to force the type of the default value to be a string, which is then
converted at run time as you would expect. Fixing this behavior would
seem to be a good project for someone (maybe me :) for v6.6...
