[Feature request] Support database comments

[okuramasafumi]

Rails 5 supports comments in database. It would be convenient if they appear in annotations.

Rails 5 supports adding comments in migrations

This would be a great feature. Anything we can help you to implement it?

PR was merged, but feature didn't work for me :(

Ruby 2.4.1, Rails and ActiveRecord 5.1.1, annotate 2.7.2, postgresql 9.5.

Used both annotate and rake annotate_models. Rake task was generated by annotate:install with this option in generated file:

'with_comment'              => true

My migration with comment:

class CommentOtherLocationsOnTasksAsDeprecated < ActiveRecord::Migration[5.1]
  def change
    change_column :tasks, :location_address, :string, comment: 'Deprecated. Use addresses field instead.'
  end
end

And this comment in schema.rb after running migration:

  create_table "tasks", id: :serial, force: :cascade do |t|
    ...
    t.string "location_address", comment: "Deprecated. Use addresses field instead."
    ...
  end

And annotation:

# == Schema Information
#
# Table name: tasks
#
#  id                 :integer          not null, primary key
#  title              :string
#  location_address   :string
#  ...

Thank you for your work @motot and @dslh!
It seems the final working version is not released yet, so I cannot close this issue.
I'm waiting for the new release, @ctran!

@ctran : You closed the issue on Feb. 14th. However, the last release I see on GH dates 2018. Is this feature here bundled in this last release (2.7.4) or not yet? If not yet, when will it be? My team wants to use that feature.
