In mysql, when you insert into an auto_increment field and you specify an id,
all future requests to insert a row without specifying the ID will still work
properly. In postgres, if you specify the id, your next insert without and
id will fail because the sequence won't have been updated.

Interesting... how do you import data from a dump with such columsn?
