Android アプリ開発のための Java 入門

MEMO

• declaration は 「宣言」 と訳しているが、「定義」 の方が適しているような気がしなくもない。
• 「インスタンス」 と 「オブジェクト」 という言葉を使うことがあるが、本文書中ではどちらも同じ意味で使用している。
• 「String オブジェクト」 という表現は、「String クラスのインスタンス」 を意味している。 (Java に限らず一般的な表現だと思う。)

1. Change your database RDS instance security group to allow your machine to access it.
   • Add your ip to the security group to acces the instance via Postgres.
2. Make a copy of the database using pg_dump
   • $ pg_dump -h <public dns> -U <my username> -f <name of dump file .sql> <name of my database>
   • you will be asked for postgressql password.
   • a dump file(.sql) will be created
3. Restore that dump file to your local database.
   • but you might need to drop the database and create it first
   • $ psql -U <postgresql username> -d <database name> -f <dump file that you want to restore>

• the database is restored

After automatically updating Postgres to 10.0 via Homebrew, the pg_ctl start command didn't work.
The error was "The data directory was initialized by PostgreSQL version 9.6, which is not compatible with this version 10.0."

Database files have to be updated before starting the server, here are the steps that had to be followed:

# need to have both 9.6.x and latest 10.0 installed, and keep 10.0 as default
brew unlink postgresql
brew install postgresql@9.6
brew unlink postgresql@9.6
brew link postgresql
