• Documentation additions are localized to a single file
• Changes consist of repetitive command snippet patterns across package managers (npm/yarn/pnpm)
• No complex logic, structural changes, or dependencies to evaluate

Pre-merge checks

❌ Failed checks (1 inconclusive)

Check name	Status	Explanation	Resolution
Title check	❓ Inconclusive	The title contains a typo ('wihtout' instead of 'without') and is partially related to the changeset—it mentions the package managers and Prisma init commands, but the actual change adds an alternative PostgreSQL initialization path, not commands 'without prisma+postgres'.	Correct the typo to 'without' and clarify whether the title should reflect 'alternative Prisma PostgreSQL initialization' or better describe the actual addition to the documentation.

Learning: The `npx prisma init` command supports the following flags: `--db` (shorthand for `--datasource-provider prisma+postgres`), `--output` (specifies output location for generated client), `--generator-provider` (defines the generator provider), `--datasource-provider`, `--url`, `--preview-feature`, and `--with-model`. These are documented valid CLI options for Prisma init command.

Learning: When the queryCompiler preview feature is enabled in Prisma ORM (v6.7.0+), it does not require Rust engines for CLI tools like `prisma migrate` or `prisma db pull`. The previous understanding that CLI tools would still need Rust binaries even with queryCompiler enabled is incorrect.

Learning: For .mdx files in the prisma/docs repository: Only flag code snippets for (1) exposed secrets with real-looking values that should be placeholders (e.g., API keys, database passwords, AWS credentials), or (2) blatant syntax errors like missing parentheses, brackets, braces, or mismatched delimiters. Do not flag code quality issues, anti-patterns, security vulnerabilities, missing error handling, unused variables, or any other bad practices, as documentation intentionally shows problematic code.

content/800-guides/080-turborepo.mdx (1)

185-185: Clarify the distinction between Prisma Postgres and self-managed PostgreSQL initialization.

The phrasing "or you can skip prisma+postgres" is misleading. The first approach (--db, which is shorthand for --datasource-provider prisma+postgres) provisions Prisma Postgres—a managed DBaaS. The alternative (--datasource-provider postgresql) configures a self-managed PostgreSQL database. These are fundamentally different offerings, not variations where one "skips" a feature.

Additionally, the post-initialization documentation states "A Prisma Postgres database" is created, which is incorrect for users following the second approach.

Recommended fix: Replace the separator with clearer language like "Alternatively, initialize Prisma with a self-managed PostgreSQL database:" and split the post-initialization documentation (lines 215-221) to clarify what each approach provisions.

Learning: For .mdx files in the prisma/docs repository: All headings and titles should use sentence case (e.g., "Getting started with Prisma ORM", "Best practices for authentication"), not title case. Exception: Always preserve exact casing for product names including "Prisma Postgres", "Prisma", "Prisma ORM", and "Prisma Data Platform".

Thank you for opening this PR, but we will not be merging this in. We would like to keep it consistent and promote the use of Prisma Postgres.

Although, we are open to adding an admonition to each guide mentioning that you can remove --db.
