laravel-mysql-to-postgres skillA
laravel-mysql-to-postgres is agent-read markdown (skill) from majdghithan/agent-skills: Migrate a Laravel application's database from MySQL/MariaDB to PostgreSQL safely. Use when moving a Laravel app to Postgres, when Eloquent/queries behave differently after switching drivers, or when planning a MySQL->Postgres cutover. Covers the migration strategy (pgloader vs query-builder), the Laravel-specific behavior differences that silently break (case sensitivity, booleans, the id-sequence trap, raw SQL, GROUP BY strictness), and a verification checklist..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

Every place you leaned on MySQL being lenient is a bug waiting on the other side. Treat a migration as an *audit of your app's lazy assumptions*, not a data transfer. ## Step 0 - The one test that surfaces half the problems Before touching real data, point `php artisan migrate` at a **fresh empty Postgres database** and watch what throws. If every migration runs clean, your schema is genuinely database-agnostic. If it throws, you just found your MySQL-only assumptions for free. ```bash # .env pointed at an empty pgsql db php artisan migrate:fresh # does the schema even build on Postgres? ``` Do not delete MySQL the day you switch. Keep it running for days/weeks until you're sure - cutovers get reverted. ## Step 1 - Move the data (pick one) …
