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


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


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

                How to migrate a Homebrew-installed PostgreSQL database to a new major version (9.3 to 9.4) on OS X. See upgraded version of this guide: http://olivierlacan.com/posts/migrating-homebrew-postgres-to-a-new-version/
              
          
    This guide assumes that you recently run brew upgrade postgresql and discovered to your dismay that you accidentally bumped from one major version to another: say 9.3.x to 9.4.x. Yes, that is a major version bump in PG land.
First let's check something.
brew info postgresql
The top of what gets printed as a result is the most important:

  
## .zshrc
# Add this to your bashrc or zshrc or whatever

port=`boot2docker info | awk -F=":" -v RS="," '$1~/"DockerPort"/ {print}' | sed 's/\"//g' | sed 's/DockerPort://'`
export DOCKER_HOST="tcp://:${port}"

## restart_graylog2_services.sh
# Stop all services in needed order.
service graylog2-web stop; service graylog2-server stop; service elasticsearch stop; service mongodb stop;

# Start all services in needed order.
# - sleep is needed, so ES and Mongo have time to startup.
service elasticsearch start; service mongodb start; sleep 5; service graylog2-server start; service graylog2-web start;
