Incomplete type description printed in annotation

[PikachuEXE]

There are several issues here, but all realated to #231

• New type description is enforced without option to keep the old one
  Should have option to keep the old one and deprecated it for next major/minor version
  I never expect this kind of change in a patch level release
• New type description is not display fully, see diff below:

-#  contact_name                          :string(255)           default(""), not null
-#  price                                         :integer
-#  annual_percentage_yield         :decimal(10, 4)
-#  last_calculate_estimate_at       :datetime
