Command history from heroku CLI setup to Postgre upgrade (MacOS)

Background

I'm using heroku to deploy my Django project. Since I bought a new Mac, it is a history and a brief explanation memo when upgrading the instance of Postgre (Is it AddOn for heroku) from the state where heroku CLI is not included.

hobby-dev Number of free records: 10,000 (from here) hobby-basic $ 9 / month Records: 10 million (upgrade here)

environment

MacOS Mojave

procedure

Step 1: Install heroku CLI

$brew install heroku/brew/heroku
$heroku login

Step 2: Check your heroku project

$heroku list
=== ****@gmail.com Apps
****1
****2
****3
****4

Now you know the app name.

Step 3:

Replace the corresponding app name found in step 2 with "".

The app name is something like "**** 1".

//Check the status of the app
$heroku pg:info -a <app name>

//Create a new database instance
$heroku addons:create heroku-postgresql:hobby-basic -a <app name>

The environment variable name "HEROKU_POSTGRESQL _ ******_ URL" that appears in ↑ will be used immediately.

//Don't break the DB? Temporary suspension
$heroku pg:wait -a <app name>

//Turn on project maintenance mode
$heroku maintenance:on -a <app name>

The following is a little careful. This command copies and pastes information from the existing database to the new database.

//Copy the information from the existing database to the new database
$heroku pg:copy DATABASE_URL as HEROKU_POSTGRESQL_******_URL -a <app name>

Since the "******" part of the environment variable name in ↑ was different from the article I saw, it is useless to copy and paste as it is, so it is necessary to check the environment variable name and customize the copy and paste.

//Connect your Django project to your new DB.
$heroku pg:promote HEROKU_POSTGRESQL_******_URL -a <app name>

//Connection confirmation
$heroku pg:info -a <app name>

//Release maintenance mode
$heroku maintenance:off -a <app name>
