## Problem part of https://github.com/neondatabase/neon/issues/11813 ## Summary of changes It costs $$$ to directly retrieve the feature flags from the pageserver. Therefore, this patch adds new APIs to retrieve the spec from the storcon and updates it via pageserver. * Storcon retrieves the feature flag and send it to the pageservers. * If the feature flag gets updated outside of the normal refresh loop of the pageserver, pageserver won't fetch the flags on its own as long as the last updated time <= refresh_period.

Local Development Control Plane (neon_local)
This crate contains tools to start a Neon development environment locally. This utility can be used with the cargo neon command. This is a convenience to invoke
the neon_local binary.
Note: this is a dev/test tool -- a minimal control plane suitable for testing code changes locally, but not suitable for running production systems.
Example: Start with Postgres 16
To create and start a local development environment with Postgres 16, you will need to provide --pg-version flag to 3 of the start-up commands.
cargo neon init --pg-version 16
cargo neon start
cargo neon tenant create --set-default --pg-version 16
cargo neon endpoint create main --pg-version 16
cargo neon endpoint start main
Example: Create Test User and Database
By default, cargo neon starts an endpoint with cloud_admin and postgres database. If you want to have a role and a database similar to what we have on the cloud service, you can do it with the following commands when starting an endpoint.
cargo neon endpoint create main --pg-version 16 --update-catalog true
cargo neon endpoint start main --create-test-user true
The first command creates neon_superuser and necessary roles. The second command creates test user and neondb database. You will see a connection string that connects you to the test user after running the second command.
