Cms: MigrationException when installing Craft on Heroku with Postgres

[al-codaio]

Description

Deploying on Heroku and when I navigate to /admin/install, I get the following on my CLI:

Exception 'craft\errors\MigrationException' with message 'An error occurred while executing the "craft\migrations\Install migration: SQLSTATE[42601]: Syntax error: 7 ERROR:  syntax error at or near "ORDER"

Steps to reproduce

1. Create project with Composer
2. Set config vars for ENVIRONMENT to "dev" and SECURITY_KEY to random string
3. Provision empty Postgres database add-on on Heroku

Additional info

• Craft version: 3.3.4.1
• PHP version: 7.3.7
• Database driver & version: pgsql 11.5
• Plugins & versions: Embedded Assets, Redactor

After that stack trace, were there any additional error details or additional stack trace(s)?

[al-codaio]

Nope that is the entire stack trace. Will try and repro again later.

[al-codaio]

Figured out the answer, was somewhat unrelated getting the admin installer to run. In Heroku's settings under Config vars, there are a series of environment variables you need to add that match your local .env file: ENVIRONMENT, SECURITY_KEY, and DB_SCHEMA.

[brandonkelly]

Glad you got it sorted!

Wrote a tutorial on getting Craft deployed on Heroku in case anyone else has issues.
