### What? This PR allows you to use a local database when using `vercelPostgresAdapter`. This adapter doesn't work with them because it requires an SSL connection and Neon's WS proxy. Instead we fallback to using pool from `pg` if `hostname` is either `127.0.0.1` or `localhost`. If you still want to use `@vercel/postgres` even locally you can pass `disableUsePgForLocalDatabase: true` here and you'd have to spin up the DB with a special Neon's Docker Compose setup - https://vercel.com/docs/storage/vercel-postgres/local-development#option-2:-local-postgres-instance-with-docker ### Why? Forcing people to use a cloud database locally isn't great. Not only they are slow but also paid. --------- Co-authored-by: Dan Ribbens <dan.ribbens@gmail.com>
