**Test**

Whether setting true or false for POSTGRES_SSL, the log output remains the same.

Start with the production configuration and the teammapper-backend TypeORM migration command shown in the log. Reproduce the migration against the configured PostgreSQL server with POSTGRES_SSL set to both true and false, then trace why the setting has no effect. Done means the false setting permits migration against a server that does not support SSL and the resulting startup behavior is documented by a test or verified log.
