The default Postgres extensions are great, and provide a lot of functionality that makes the Railway hosted version much more useful than a vanilla Postgres install. With that said, there are some additional extensions that are useful in some use cases, but may not be as widely needed as the default extensions. Are there any plans to allow for additional extensions to be installed? Even allowing extensions just from very well-known and trusted developers (ex: https://github.com/citusdata/pg_cron) would be very helpful.
