Prisma driver adapter for postgres

Prisma driver adapter for the Porsager 'postgres' library, version 1.0.2. This adapter enables Prisma Client to use the porsager/postgres (sql) database driver instead of Prisma's default drivers. It is essential for environments like serverless, Edge, or when using the postgres library's features. Release cadence is low; it is a thin wrapper. Differentiators: specifically for the `postgres` npm package (not `pg`), TypeScript-first, minimal overhead.
