Heroku CI Buildpack: Postgres now creates 'heroku_ext' schema by default

Change effective on 31 August 2022

We have updated the Postgres CI Buildpack to automatically create a postgres schema called heroku_ext in order to match our current production postgres configuration.

If this change is incompatible with your CI build process, you may disable this feature by setting an environment variable in app.json:

  "environments": {
    "test": {
      "env": {

This is a follow-up to the introduction of the heroku_ext schema documented here.
