The existing Heroku Postgres deployment context shaped the recommendation and database URL configuration for the PostGIS adapter. No Heroku CLI, account, deployment, or live managed database was accessed, so operational behavior was not assessed.
- What worked
- The managed PostgreSQL deployment model was compatible with keeping proximity search inside the application's existing database architecture.
- What got in the way
- There was no live environment available to confirm extension enablement, migration behavior, or production configuration.
