herokuにうまくrailsのDBが反映されない

herokuでrailsappをdeployしたいのですがdbがうまく反映されません。db以外のものはdeployできています。herokuのdbのファイルで指定すればいいんでしょうか？database.ymlは

# SQLite version 3.x
#   gem install sqlite3
#
#   Ensure the SQLite 3 gem is defined in your Gemfile
#   gem 'sqlite3'
#
default: &default
  adapter: sqlite3
  pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %>
  timeout: 5000

development:
  <<: *default
  database: db/development.sqlite3

# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
  <<: *default
  database: db/test.sqlite3

production:
  <<: *default
  adapter: postgresql
  username: tpevkaavpicadp
  host: ec2-54-163-249-237.compute-1.amazonaws.com:5432
  database: daopn9j0e9smh4
  password: 6b08b34fc6482c78b83595d037e2fd8da4e618bcd7ff78790386d71131bda18c
  database: db/production.sqlite3

でschemeは

# This file is auto-generated from the current state of the database. Instead
# of editing this file, please use the migrations feature of Active Record to
# incrementally modify your database, and then regenerate this schema definition.
#
# Note that this schema.rb definition is the authoritative source for your
# database schema. If you need to create the application database on another
# system, you should be using db:schema:load, not running all the migrations
# from scratch. The latter is a flawed and unsustainable approach (the more migrations
# you'll amass, the slower it'll run and the greater likelihood for issues).
#
# It's strongly recommended that you check this file into your version control system.

ActiveRecord::Schema.define(version: 20171007030215) do

  create_table "comments", force: :cascade do |t|
    t.datetime "created_at", null: false
    t.datetime "updated_at", null: false
    t.text "comment"
    t.integer "user_id"
    t.integer "post_id"
  end

  create_table "posts", force: :cascade do |t|
    t.datetime "created_at", null: false
    t.datetime "updated_at", null: false
    t.text "content"
    t.integer "user_id"
    t.text "location"
    t.integer "gender"
    t.text "line_id"
  end

  create_table "users", force: :cascade do |t|
    t.datetime "created_at", null: false
    t.datetime "updated_at", null: false
    t.integer "icon_id"
    t.integer "icon_back_id"
  end

end

なんですがcommenttableが反映されないのとなぜかposttableも一部しか反映されず。。。

20171022_追記

下記のmigrationファイルが反映されていないです。開発環境だとされています。

class RenameSexColumnToGender < ActiveRecord::Migration[5.1]
  def change
    rename_column :posts, :sex, :gender
  end
end

class CreateComments < ActiveRecord::Migration[5.1]
  def change
    create_table :comments do |t|

      t.timestamps
    end
  end
end

class Comments < ActiveRecord::Migration[5.1]
  def change
    add_column :comments, :comment, :text
    add_column :comments, :user_id, :integer
    add_column :comments, :post_id, :integer
  end
end
