No, the problem is that you're specifying string constants with
double-quotes, not single-quotes. ;) Double-quotes are for identifiers,
not constants.

Change it to read like this, and you'll be set:

address_type VARCHAR(30)
  DEFAULT 'unknown'
  NOT NULL
  CHECK(address_type IN
        ('unknown', 'forged', 'proxy', 'temporary', 'permanent'))
