# Where they use a cloud watch event from ECS to notify a SNS topic. We're

How to copy production database on AWS RDS(postgresql) to local development database.
  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
