## Problem We have this set of test utilities which duplicate a tenant by copying everything that's in remote storage and then attaching a tenant to the pageserver and storage controller. When the "copied tenants" are created on the storage controller, they start off from generation number 0. This means that they can't see anything past that generation. This issues has existed ever since generation numbers have been introduced, but we've largely been lucky for the generation to stay stable during the template tenant creation. ## Summary of Changes Extend the storage controller debug attach hook to accept a generation override. Use that in the tenant duplication logic to set the generation number to something greater than the naturally reached generation. This allows the tenants to see all layer files.
Control Plane and Neon Local
This crate contains tools to start a Neon development environment locally. This utility can be used with the cargo neon command.
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.
