## Problem Preparation for https://github.com/neondatabase/neon/issues/10851 ## Summary of changes Add walproposer `safekeepers_generations` field which can be set by prefixing `neon.safekeepers` GUC with `g#n:`. Non zero value (n) forces walproposer to use generations. In particular, this also disables implicit timeline creation as timeline will be created by storcon. Add test checking this. Also add missing infra: `--safekeepers-generation` flag to neon_local endpoint start + fix `--start-timeout` flag: it existed but value wasn't used.
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.
