### What? Turborepo fails to compile due to type error in the generated drizzle schema. ### Why? TypeScript may not include the module augmentation for @payloadcms/db-postgres, especially in monorepo or isolated module builds. This causes type errors during the compilation process of turborepo project. Adding the type-only import guarantees that TypeScript loads the relevant type definitions and augmentations, resolving these errors. ### How? This PR adds a type-only import statement to ensure TypeScript recognizes the module augmentation for @payloadcms/db-postgres in the generated drizzle schema from payload, and there is no runtime effect. Fixes #12311 --> 
Payload Drizzle Adapter
The Drizzle package is used by db-postgres and db-sqlite for shared functionality of SQL databases. It is not meant to be used directly in Payload projects.
