## Problem Spun off from https://github.com/neondatabase/neon/pull/6394 -- this PR is just the persistence parts and the changes that enable it to work nicely ## Summary of changes - Revert #6444 and #6450 - In neon_local, start a vanilla postgres instance for the attachment service to use. - Adopt `diesel` crate for database access in attachment service. This uses raw SQL migrations as the source of truth for the schema, so it's a soft dependency: we can switch libraries pretty easily. - Rewrite persistence.rs to use postgres (via diesel) instead of JSON. - Preserve JSON read+write at startup and shutdown: this enables using the JSON format in compatibility tests, so that we don't have to commit to our DB schema yet. - In neon_local, run database creation + migrations before starting attachment service - Run the initial reconciliation in Service::spawn in the background, so that the pageserver + attachment service don't get stuck waiting for each other to start, when restarting both together in a test.
