Moving a database to a new database instance

  • Use pg_dump to dump the exsting database into a file
  • Edit the user name to fit the new database to be used
  • use psql to load the data into the new database

Example: Dumping the heroku database and loading it on AWS

First dump the Heroku database
pg_dump -h ec2-52-87-121-192.compute-1.amazonaws.com -U ud6dfgef6bi48k -d d1hlu2cr9ta2p3 >db_dump
Edit the user name from "ud6dfgef6bi48k" to "cobudget"
sed -e 's/Owner: ud6dfgef6bi48k/Owner: cobudget/' -e 's/OWNER TO ud6dfgef6bi48k/OWNER TO cobudget/' db_dump >db_loadable
Create the new database
createdb -h cobudget-prod.cird90svlmvv.us-west-2.rds.amazonaws.com -U cobudget cobudget_prod
Load the new database with the previously dumped data
psql -h cobudget-prod.cird90svlmvv.us-west-2.rds.amazonaws.com -U cobudget -d cobudget_prod <db_loadable
The load should be executed with no errors.
To look around in the database, use psql
psql -h cobudget-prod.cird90svlmvv.us-west-2.rds.amazonaws.com -U cobudget -d cobudget_prod
In case something goes wrong, you can always delete the database
dropdb -h cobudget-prod.cird90svlmvv.us-west-2.rds.amazonaws.com -U cobudget cobudget_prod
and restart with creating the new database.
