Could you just move this to a section within that document please? Otherwise good write up!


e.g: `cf connect-to-service tdp-backend-qasp tdp-db-dev`

After connection to the DB is made (the step above will make a psql connection), then the following Postgres commands have to run:

1. List the DBs: `\l`
2. find the associated DB name with instance. E.g: `tdp_db_dev_qasp`

Does it make sense to have a section or command on how to take a backup/dump?

3. use the following command to delete the DB: `DROP DATABASE {DB_NAME}`
4. use the following command to create the DB: `CREATE DATABASE {DB_NAME}`

After the DB is created, since the database is cinoketely empty, we will need to redeploy the app again to create tables (or alternatively we can restore a good backup), and then we should run populate stt command to add STT data to the empty DB

`./manage.py populatestts`
