sequence.update() doesn't support an options argument

[aleclarson]

db.table('posts').update({}, options)

...where options can have these properties:

• returnChanges: true Include a changes array in the response, with an {old_val, new_val} pair for each updated row.

• returnChanges: false Exclude the changes array. (the default behavior)

• returnChanges: "always" Include a changes array, with an {old_val, new_val} pair for every row (even if not updated).
