Heroku buildpack: pgbouncer allows one to run pgbouncer in a dyno alongside application code. This is different from PgBouncer hosted as a separate infrastructure components (that test is covered in databases/heroku-pgbouncer)
The environment variable DATABASE_URL_PGBOUNCER should point to a postgres database.
Please check our internal 1Password E2E vault for a ready-to-use environment variable or
set up your own database and set the environment variable accordingly.
