表題の通りですが、defaultはsqlite3が入っているrailsですが、最初からpostgresqlを入れてherokuにdeployする際に発生した問題についてメモ

herokuのdev centerにdefaultの設定方法とか詳細書いてあるので、そちらを参照して頂きたいのですが、

新規のrailsアプリ立ち上げの際にdefaultのdbをpostgreに設定する

$ rails new projectname -d postgresql

そうすると下記の様にデフォルトでconfig/database.ymlの設定が変化します。

development:
  adapter: postgresql
  encoding: unicode
  database: no-cancel_development
  pool: 5
  username: no-cancel
  password:

  # Connect on a TCP socket. Omitted by default since the client uses a
  # domain socket that doesn't need configuration. Windows does not have
  # domain sockets, so uncomment these lines.
  #host: localhost
  #port: 5432

  # Schema search path. The server defaults to $user,public
  #schema_search_path: myapp,sharedapp,public

  # Minimum log levels, in increasing order:
  #   debug5, debug4, debug3, debug2, debug1,
  #   log, notice, warning, error, fatal, and panic
  # The server defaults to notice.
  #min_messages: warning

# 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:
  adapter: postgresql
  encoding: unicode
  database: no-cancel_test
  pool: 5
  username: no-cancel
  password:

production:
  adapter: postgresql
  encoding: unicode
  database: no-cancel_production
  pool: 5
  username: no-cancel
  password:

gemfileも上記コマンドで生成した場合は下記のようにpgになっています。

//gemfile
gem 'pg'

databaseの名前は上記で設定した際のprojectname_development,_test等のようになっています。
ここまででpostgreの設定は終了

db作成でのエラー対応

$ rake db:create
$ rake db:migrate

上記のコマンドを打つとエラーが下記のように出ます。
しかしdbディレクトリは存在しています。

could not connect to server: No such file or directory
	Is the server running locally and accepting
	connections on Unix domain socket "/var/pgsql_socket/.s.PGSQL.5432"?

そこで一応再確認

$ psql
psql: could not connect to server: No such file or directory
	Is the server running locally and accepting
	connections on Unix domain socket "/var/pgsql_socket/.s.PGSQL.5432"?

解決としては一旦postgreをデフォルトでsetするのをやめてgemfileで分岐するようにしました。
productionはpgでdevelopmentはsqlite3という事で。

それでまぁ無事に動いたようなのでこれからごりごり開発して行きます。
